Email list affiliate marketing
Email list affiliate marketing means sharing useful recommendations with people who have chosen to hear from you, and earning a commission when they buy through your links. It takes time to build trust and an audience, and income is not guaranteed.
Open the interactive guide (checklist, video, read-aloud) →In plain words
- Choose a topic you know and write helpful emails about it.
- People choose to join your list.
- You may earn commission when readers buy through your links.
- Ask permission before sending marketing emails.
- It takes time, and you may earn nothing.
Who it suits
It suits people who enjoy writing, can stick with a topic, and are willing to build an audience gradually. It is less suited to anyone looking for quick or dependable income.
Readers may value useful advice that helps them choose products or solve a problem. A company may pay you commission if someone buys through your affiliate link, but there is no guarantee of sales or income.
Step by step
- Choose a topic you can write about regularly. Pick a clear subject, such as home cooking, books or personal technology. Write down questions people interested in it want answered, and choose questions you can genuinely help with. About 1-2 hours.
- Choose an email service and check its terms. Compare the features and current pricing of possible services before opening an account. Shopify lists Mailchimp, MailerLite and Shopify Messaging as email-marketing tools; the cited page does not state their fees, so check current pricing and terms. Shopify About 30-60 minutes.
- Make a clear signup page. Explain what readers will receive and how often you expect to email them. Make the signup an active choice; do not add people without their knowledge. About 1-3 hours.
- Record permission and make unsubscribing clear. Set up a reliable way to record when and how someone agreed to receive emails, and include a clear way to unsubscribe. In the UK, marketing emails to individuals generally need consent, unless the existing-customer soft opt-in applies; that exception is for your own customers, not prospective customers or bought-in contacts. ICO About 1-2 hours.
- Choose affiliate programmes that suit your topic. Look for programmes whose products are relevant to your readers. Read how referrals are tracked, when commissions are paid and what rules apply; programmes are often free to join, but check each programme's terms. Shopify About 1-3 hours.
- Write a helpful welcome email. Thank readers for joining, explain what kind of emails they can expect and give them something useful before promoting products. Keep the message relevant to the reason they signed up. About 30-90 minutes.
- Write useful guides and disclose affiliate links. Create practical guides or honest comparisons, and include links only when they help readers. Make promotional content clear: UK advertising guidance gives “Ad” as an example label. ASA About 2-4 hours per guide.
- Send emails at a manageable pace. Choose a schedule you can keep, rather than sending more emails than you can manage. Check whether readers open, click or unsubscribe, and use that information to make future emails clearer and more useful. About 30-60 minutes each week.
- Keep records and check the rules where you live. Record commissions and costs, and keep copies of programme terms and relevant business records. Check the tax and marketing rules that apply to your location; possible earnings are not a promise. About 30 minutes each month.
Your first 15 minutes
Choose a topic, draft a clear signup invitation and welcome email, and check the email-marketing rules that apply where you live before inviting subscribers.
The money
You do not set the commission rate: each affiliate programme sets its own terms, so check them before promoting a product. Track commissions and your costs, such as email tools, and judge whether the work is worthwhile without assuming you will earn a particular amount.
Example only: UK week: £20 commission income − £5 costs = £15 before tax. Ireland week: €20 commission income − €5 costs = €15 before tax. These are made-up figures to show the calculation, not an earnings forecast.
The rules
You can do affiliate email marketing in the UK and Ireland, but you must follow the relevant email-marketing, data-protection, tax and advertising rules. There's no general affiliate-marketing licence or age rule. Before you join, check the terms of the email service and affiliate programme you want to use.
UK and Northern Ireland
- Permission and unsubscribe. You generally need consent to send marketing emails to individuals. The existing-customer soft opt-in may apply if you meet its conditions. Don't hide who you are. Give people a valid contact address so they can opt out. ICO
- Tax and Self Assessment. The trading allowance is £1,000 per tax year. This is your gross income before expenses. If your income is above that amount, you must tell HMRC. If you need to register for Self Assessment, do so by 5 October after the end of the tax year in which you had income to report. GOV.UK Tax Help for Hustles GOV.UK
- Advertising disclosure. Clearly label affiliate advertising. The ASA gives “Ad” as an example. ASA
- ICO data protection fee. Use the ICO self-assessment tool to check whether you need to pay a fee for your data processing. The ICO's wholesale and retail guidance says you need to pay a fee if you advertise another person's business, goods or services. ICO
- Eligibility. There's no general age rule for affiliate email marketing. Check the terms of your email service and affiliate programme.
Ireland
- Permission for marketing emails. As a general rule, you need a person's affirmative consent before you send them marketing emails. They can withdraw their consent. A limited customer exception may apply to a business's own similar products or services. The customer must have had an easy, free chance to object when their details were collected. Each message must offer a chance to object. The sale or electronic marketing use of their details must have been within the previous 12 months. Data Protection Commission
- Right to object. People can object at any time to direct marketing, including related profiling. You must make this right clear and explain it separately. Data Protection Commission
- Data protection and registration. GDPR applies to most data processing in Ireland, alongside the Data Protection Act 2018 and the ePrivacy Regulations. There's no general registration or licence requirement for electronic marketing. Data Protection Commission Data Protection Commission
- Tax and Revenue. If you're a PAYE worker, register for self-assessment using Form 11 if your taxable non-PAYE income is over €5,000 or your gross non-PAYE income is over €30,000. Below those thresholds, declare your income on Form 12 through myAccount. OpenAccountants
- Advertising disclosure. Label commercial influencer content with “#Ad”. The CCPC advises you to label it if you're in doubt. CCPC
- Eligibility. There's no general age rule for affiliate email marketing. Check the terms of your email service and affiliate programme.
