How To Promote Affiliate Links Through Email Marketing 2021

You have probably heard it a hundred times: the money is in the list. But knowing that does nothing for you if nobody tells you how to actually use that list to make affiliate sales. Most people build an email list, blast out a few buy-now emails, wonder why no one is clicking, and give up. The real problem is not their niche or their offer. It is that they are missing a handful of specific habits that separate affiliates who make consistent commissions from those who spin their wheels.

In this post I am breaking down all 13 tips Alston Godbolt has picked up from years of affiliate email marketing. Some of these came the hard way, after sending tens of thousands of emails and watching deliverability tank. Others came from studying what the best marketers in this space were doing. None of them are complicated. All of them are actionable today.

Tip 1: Use a Custom Domain Email Address

If you are sending affiliate emails from a Gmail, Hotmail, or Yahoo account, those emails are getting flagged as spam before they even reach your subscriber’s inbox. This is one of the most common mistakes beginners make, and it costs them a large portion of their potential reach right from the start.

The fix is straightforward. Register a domain through a hosting provider like Bluehost or GoDaddy, then use that hosting back office to create a custom email address. Something like mail.yourdomain.com looks legitimate to email servers, builds credibility with subscribers, and delivers at a much higher rate than a free email provider. Bluehost entry-level hosting starts at around three dollars per month, which is a small cost given how much deliverability matters to your affiliate income over time.

Tip 2: Rotate Your Sending Domain Every 6 Months

Here is something most beginners never hear: even a solid custom domain has a shelf life. As you send more emails, some subscribers will inevitably mark your messages as spam. Every one of those spam reports chips away at the reputation of that sending address. Over time your deliverability on services like Gmail and Hotmail will decline, even if your content is genuinely useful.

After sending somewhere between 20,000 and 40,000 emails from a single domain, Alston noticed deliverability starting to soften. The solution is to rotate to a fresh sending domain every six months. You do not need to buy a new hosting plan each time. Inside your hosting control panel, commonly called cPanel, you can create new email addresses and delete old ones in just a few minutes. It is a small administrative habit that protects a significant chunk of your affiliate income over the long term.

Tip 3: Email Your List Every Single Day

This one makes beginners uncomfortable. It made Alston uncomfortable too when he first heard it. The fear is that you will annoy people, come off as spammy, or drive unsubscribes. But here is what actually happens when you email every day: the people who are genuinely interested in what you have to say stay on your list, and the people who were never going to buy leave. That is not a bad outcome. That is list pruning, and it makes your list healthier and more responsive over time.

Your competitors are not waiting. Some of the most successful affiliate marketers in this space email more than once per day. Every email you skip is an opportunity a competitor takes. Once per day is the floor. Twice per day is not out of the question if you have valuable things to share. The more frequently you email with substance, the more you prune your list down to people who are genuinely interested, and the better your conversion rates become.

Tip 4: Mix Helpful Content Into Every Week, Not Just Offers

If every email you send is a push to buy something, your subscribers will start ignoring you quickly. The buy-buy-buy approach burns out a list because people stop trusting that you have their interests in mind. They begin to feel like a target instead of an audience, and their engagement drops along with their purchase intent.

The better approach is to mix genuinely helpful, no-pitch content into your email rotation. A list-style email like “10 things I wish I knew before starting affiliate marketing” or “5 tools that cut my work in half” gives real value without asking for anything. When you eventually send an offer email, your subscribers are far more receptive because you have already proven you know what you are talking about. One formatting note from the video: odd-numbered lists, those with 3, 5, 7, or 9 items, consistently outperform even-numbered ones in terms of open rates and engagement. Something about the incompleteness of an odd number keeps readers curious.

Tip 5: Tell Personal Stories

Of all the tactics in this list, storytelling is the one that separates average affiliate email marketers from the ones who build genuinely loyal audiences. People do not click buy-now links from strangers. They click them from people they feel like they actually know.

Alston shared two specific examples from his own list. The first was an email about having twins and the financial pressure that pushed him to start his online business. He closed the email with a link to a 15-day program he was promoting. That email generated a high click-through rate not because the offer was special, but because subscribers could see he was a real person with real stakes in the outcome. The second example was an email about his eye surgery. He is diabetic and has had two eye surgeries, a detail most of his YouTube audience did not know. He tied that health struggle directly to why he built his online business. The result was a high open rate and strong conversions on the same 15-day program. The formula is: reveal something real, connect it to the subscriber’s situation, then offer the next step as a natural conclusion to the story.

Tip 6: Build an Autoresponder Sequence

An autoresponder is a series of pre-written emails that goes out automatically after someone joins your list. It is the closest thing to passive income you will find in email marketing. Once you write the sequence and configure the timing, it works for you around the clock without you touching it again.

Alston uses GetResponse for his autoresponder setup, which offers a 30-day free trial. He pairs it with ClickFunnels on the front end for landing pages. When building your sequence, focus on three goals: tell stories that build trust over multiple emails, address the objections your audience has before they even voice them, and return repeatedly to the pain points that caused someone to opt in to your list in the first place. Get those three elements working in sequence and you will see leads and sales generated while you sleep, not just when you are actively at your desk sending emails.

Tip 7: Send Broadcast Emails for Timely Content

Autoresponder sequences run automatically, but broadcast emails are the ones you write in real time, tied to something happening now: a new YouTube video you just uploaded, a product launch, a fresh tip you discovered, or breaking news in your niche. These are one-time sends to your full list, and they serve a different purpose than your evergreen sequence.

Alston sends a broadcast email every time he uploads a new YouTube video. This cross-promotes his content, sends warm traffic to his channel right after upload, and signals to YouTube that real people are watching immediately after a video goes live. That early engagement quality signal helps his videos reach more people organically. If you have a blog post, a new affiliate discovery, or a lesson from a recent mistake, that is broadcast material. The key is that it feels current and personal, which is exactly what differentiates it from the automated evergreen sequence running in the background.

Tip 8: Include a Call to Action in Every Email

Every email needs to tell people what to do next. Without a clear call to action, subscribers read your message, think “interesting,” and close their inbox. You lose the moment. It does not matter how compelling your story is if there is no bridge to the next step.

Alston uses a three-part framework: hook, story, offer. The hook is a subject line or opening line that makes people want to read further. Something like “The real reason I almost quit” or “Three things I stopped doing that changed my commissions” creates forward momentum. The story answers the question the hook posed. The offer is the call to action: “click here to start the 15-day challenge,” “watch this free training,” or “get started today.” This structure works in every niche and for every type of affiliate product. Build the habit of ending every single email with a clear, specific next step, because readers who finish your email without a directive will simply move on to the next thing.

Tip 9: Subscribe to Your Competitors’ Email Lists

One of the most underused research tools in affiliate email marketing is also one of the simplest: sign up for your competitors’ lists. Alston keeps a dedicated junk email address for this purpose and uses it to opt into every email list he encounters in the internet marketing space, whether through a paid ad, a YouTube video, or a Facebook post.

Reading what competitors send teaches you what is working right now, not six months ago. If someone is paying to run ads driving subscribers to a list, they have already tested whether those subscribers convert. Watching what they do with that list gives you a window into proven subject lines, content angles, offer sequencing, and email frequency. The goal is not to copy. The goal is to study. You take what seems to be working, filter out what does not fit your voice or your audience, and apply those insights to your own strategy. Markets evolve and what worked a year ago may not work today, so staying plugged into competitor lists keeps you current on what is actually moving people right now.

Tip 10: Keep Affiliate Links to 3 or Fewer Per Email

This tip is purely mechanical but it has a real impact on deliverability. When an email filtering system scans outgoing messages, the number of affiliate links in an email is one of the signals it checks. Too many links and the message looks like spam to the algorithm, which means it lands in the promotions tab or the spam folder instead of the primary inbox.

The practical ceiling is three affiliate links per email, and in most cases one is the right number. Lead with your primary offer, include the link once in the body and once at the end in your call to action, and leave it there. Stuffing an email with five or six different affiliate links not only risks your deliverability but also creates decision paralysis in the reader. Give people one clear thing to do and they are much more likely to do it. Simplicity is not laziness here. It is strategy.

Tip 11: Test Your Emails on a Regular Schedule

Most people set up their autoresponder once and never look at it again. That approach leaves real money on the table. Email performance is not static. A subject line approach that worked last quarter may be getting ignored today. An offer that converted at 4% in the spring might be at 1% by fall after the market shifts. The only way to know is to check your numbers.

Alston recommends auditing your email analytics at least every few weeks. Look at deliverability rates first: are your emails actually reaching inboxes? Then check open rates: are subscribers seeing your subject lines and deciding to read? Finally look at click-through rates: are readers taking action after opening? Each of these numbers points to a different problem. Low deliverability points to a domain reputation or list quality issue. Low open rates point to weak subject lines. Low click-through rates point to a mismatch between the story in the email and the offer at the end. Diagnose the right layer before making changes, otherwise you end up fixing the wrong thing.

Tip 12: Write Like You Are Talking to a Friend

Alston made this mistake early. He formatted his emails like business communications: capitalized headings, formal language, the kind of tone you would find on a corporate website. The problem is that people do not open emails from businesses. They open emails from people they like and trust.

If your email reads like a memo, it will get ignored at the same rate as a memo. If it reads like a message from a friend who found something useful and wanted to share it, open rates climb. That shift in tone does not mean being sloppy or unprofessional. It means using first-person language, keeping sentences short, referencing real things happening in your life or your business, and writing in the same register you would use in a text message to someone you actually know. Your subscribers opted in to hear from you specifically. Sound like you, not like a brand.

Tip 13: Save Every Email That Converts

Every time an email you sent generates a sale, or every time you receive an email from a competitor that causes you to click and buy, save it. Copy it to a folder, a Google Doc, or a plain text file on your desktop. You now have evidence that this exact combination of subject line, story, and call to action has worked on at least one real human being with money to spend.

That collection becomes a swipe file. When you are staring at a blank email with no idea how to start, go back to what has already proven itself. Analyze it carefully. What was the hook? What made the story feel personal and specific? How was the call to action phrased and where did it appear in the email? You are not replicating it word for word. You are extracting the underlying structure and using that structure to write something fresh that serves your current offer. A well-built swipe file, added to consistently over months and years, becomes one of your most valuable business assets because it is built on data, not theory.

Honest Drawbacks of Affiliate Email Marketing

These 13 tips work, but affiliate email marketing comes with real challenges worth naming before you commit serious time to it.

Building the list takes time before it pays off. Before any of these tactics can do their job, you need people to email. If you are starting from zero subscribers, your first several months will be about list-building before they are about promoting. That means paid traffic, content marketing, lead magnets, or a combination of all three. Budget time and money for the growth phase before expecting income from the monetization phase.

Domain management is ongoing administrative work. Rotating sending domains every six months, creating new addresses in cPanel, and tracking which domain is currently active sounds simple in theory. In practice it is easy to forget, and then wonder six months later why deliverability softened. Set a calendar reminder at the six-month mark from your first send and treat it like a recurring business expense you have to schedule.

Daily emailing is harder to sustain than it sounds. You will not always have something valuable to say. On slow days, the temptation is to skip, or to send something weak just to hit the frequency target. Neither is a good option. Build a content bank of stories, tips, and observations ahead of time so you always have material ready to go even when inspiration is not coming.

Unsubscribes are part of the process, not a sign of failure. When you email every day, some people will leave. That is the system working as designed. A smaller, highly engaged list will always outperform a large, disengaged one in terms of actual commissions earned. Keep your focus on the subscribers who stay and engage, not on the ones who leave.

Find Your X

Email marketing works best when you are promoting an offer that genuinely fits your audience and your own background. If you are still figuring out which affiliate niche or income model is the right match for the skills and interests you already have, the Platform Proof Finder walks you through a short quiz and matches you with an income path built around what you already bring to the table. Start there before you build your list so you know exactly what you are building it around.

Frequently Asked Questions

How often should I email my affiliate list?

At minimum, once per day. Some successful affiliate marketers email twice per day. The goal is not to overwhelm people but to stay consistently present. Subscribers who find daily emails too frequent will unsubscribe, and that is fine. The ones who stay are more likely to buy because they are genuinely engaged with your content and trust your recommendations.

What is the best autoresponder for affiliate marketers?

Alston recommends GetResponse, which offers a 30-day free trial and handles the full email marketing setup including automation, list segmentation, and analytics. He uses it on the back end of a ClickFunnels lead capture process. Other solid options include AWeber, ActiveCampaign, and ConvertKit. The platform matters less than the habit: pick one and use it consistently rather than switching tools every few months chasing marginal feature differences.

How many affiliate links should I include in one email?

No more than three, and in most cases one is the correct number. Too many links signals spam to email filtering algorithms and reduces the odds your email reaches the primary inbox. It also creates decision paralysis for the reader, which typically means they click nothing. Choose one offer per email, link to it clearly in the body and once more at the end as your call to action, and let the email do one job well.

What is the difference between an autoresponder and a broadcast email?

An autoresponder is a pre-written sequence that sends automatically after someone opts in, usually on a fixed schedule such as Day 1, Day 3, Day 7, and so on. It is evergreen content that every new subscriber gets in the same order. A broadcast email is a one-time send to your full list, tied to something happening right now: a new video upload, a product launch, or a time-sensitive tip. You need both. The autoresponder builds trust and promotes offers on autopilot. Broadcasts keep your list feeling like they are hearing from a real person with something relevant to say today.

How do I avoid landing in the spam folder?

Use a custom domain email address instead of a free provider like Gmail or Hotmail. Rotate that sending domain every six months as your email history builds up and inevitably accumulates a few spam complaints. Keep your affiliate link count low per email. Send consistent, genuinely helpful content so subscribers do not flag you out of frustration. And use a reputable email service provider with strong deliverability infrastructure. None of these guarantees inbox placement every time, but combining them consistently reduces the spam folder risk significantly compared to ignoring all of them.

How do I know if my emails are actually converting?

Track three numbers inside your email platform. First is deliverability rate: are your emails reaching inboxes at all. Second is open rate: are subscribers seeing your subject lines and choosing to read. Third is click-through rate: are readers taking action after opening. A weak deliverability rate usually points to domain reputation. A weak open rate usually points to subject lines that are not compelling enough. A weak click-through rate usually points to a mismatch between the promise the email made and the offer you are pointing to. Fix one layer at a time and give any change at least two to three weeks before drawing conclusions from the data.

Do I need a website to do affiliate email marketing?

You need a domain, but you do not need a full website at the start. What you need at minimum is a landing page to collect email addresses and a custom email address on that domain for sending. ClickFunnels lets you build effective lead capture pages without a traditional website. The custom domain is non-negotiable because it protects your deliverability. A full blog or content site helps with organic traffic over time and can feed new subscribers to your list, but it is not required before your first opt-in.

What makes a good email subject line for affiliate offers?

Curiosity and specificity tend to outperform generic clickbait. A subject line like “The real reason I almost quit affiliate marketing” beats “Check this out” every time. Personal stakes work well, and so do odd-numbered lists as in “5 things I stopped doing” or “7 mistakes I made in year one.” The best way to find what works for your specific audience is to test different subject line styles, check your open rate data, and repeat the approaches that perform. Save every subject line you personally open from other marketers’ emails. Those are your data points for what catches attention in a crowded inbox.
