Can I Add Past Customers to My Email Marketing List?


Email marketing is a powerful tool for businesses to nurture relationships, promote new products or services, and boost sales. However, a common question that arises is, can you add past customers to your email marketing list? While it may seem like a great way to re-engage with former clients, it’s essential to consider legal and ethical guidelines before doing so.

Here’s a summary – but please always do your research as privacy laws are changing all the time.

Understanding Email Marketing Laws

Before adding anyone to your email marketing list, it’s crucial to be aware of the regulations that govern email marketing in your country. In most jurisdictions, the rules for email marketing are quite strict to protect individuals from spam.

  • GDPR (General Data Protection Regulation): In the EU, GDPR requires that businesses obtain explicit consent from individuals before adding them to email lists. Even if someone has made a purchase, this doesn’t automatically grant permission to send them marketing emails.
  • CAN-SPAM Act: In the US, the CAN-SPAM Act governs email marketing. While it’s slightly more lenient than GDPR, it still requires businesses to allow recipients to opt-out of marketing communications and clearly identify the email as an advertisement.
  • Privacy Act 1988 & Spam Act 2003 (Australia): In Australia, businesses need consent to send marketing emails. Customers who have given explicit or inferred consent (such as by making a purchase) can be contacted, but they must have the ability to unsubscribe at any time.

Understanding the laws that apply in your region will help you avoid hefty fines and protect your business’s reputation.

Types of Consent: Implied vs. Explicit

When it comes to email marketing, consent can be categorized as either implied or explicit.

  • Implied Consent: If someone has made a purchase or enquired about your business, they may have provided implied consent to receive emails. However, this consent is often limited to transactional emails, such as order confirmations or updates related to their purchase.
  • Explicit Consent: This is the gold standard for email marketing. It means that the person has taken a clear action, such as ticking a checkbox, to indicate that they agree to receive marketing emails. This is the safest and most compliant way to add someone to your email list.

Can You Add Past Customers to Your List?

So, can you add past customers to your email marketing list? The short answer is: only if you have their consent.

If a past customer has opted in to receive marketing emails from you, then you’re free to add them to your list. If not, you need to obtain explicit consent before sending them marketing materials.

If your past customers haven’t opted in, consider sending them a one-time email asking if they’d like to join your mailing list. Make the benefits clear—such as exclusive offers, updates on new products or services, or helpful content—so they have a reason to subscribe. Always provide a clear opt-out mechanism, allowing them to easily unsubscribe if they’re not interested.

Best Practices for Email Marketing

To ensure you’re following best practices and respecting your customers’ privacy, consider the following tips:

  1. Use Double Opt-In: When someone signs up for your email list, send them a confirmation email asking them to verify their subscription. This helps ensure that only those genuinely interested will receive your emails.
  2. Segment Your List: Consider creating different segments for customers and prospective leads. You might use one list for transactional emails (order updates, etc.) and another for marketing campaigns. Past customers may respond better to personalized offers or content based on their previous purchases.
  3. Provide Value: Ensure that your emails provide real value to the recipient. People are more likely to stay subscribed if they feel they’re receiving helpful or relevant information. Avoid spamming them with overly frequent messages.
  4. Regularly Clean Your List: Periodically review your email list and remove inactive subscribers. This helps improve your open rates and ensures you’re only communicating with engaged customers.
  5. Always Include an Opt-Out Option: Every marketing email you send must contain an unsubscribe link. Make this process simple and clear to avoid frustrating your audience and staying compliant with the law.

Adding past customers to your email marketing list is possible, but only with the proper consent. Always follow the relevant legal requirements and best practices to build trust with your audience. Email marketing works best when it’s done ethically and respectfully, so ensure that your past customers have willingly opted in and that they continue to receive value from your communications.
