How to manage do not call list requests for email

Managing do not call (DNC) requests specifically for email requires a separate process from phone numbers, as email rules are distinct. Always honor direct opt-out requests for email, and keep clear records of these instructions.

Email vs. phone DNC rules: what’s the difference?

This information is for educational purposes only and is not legal advice. Consult with a qualified attorney for specific legal guidance.

Rules governing email outreach, primarily CAN-SPAM in the US, are different from those for phone calls (TCPA, TSR). For email, the focus is on clear identification, an accurate subject line, and a functioning opt-out mechanism. The National Do Not Call Registry, for example, applies to phone numbers, not email addresses.

This means a seller might be on the DNC list for phone calls but could still receive emails from you, provided you adhere to email-specific regulations. You must treat each communication channel with its own set of rules. Do not assume compliance in one channel covers another.

Recording email opt-out requests

When a seller explicitly asks to be removed from your email list, you must honor that request promptly. The most straightforward way to manage this is to use a CRM or email marketing platform that tracks opt-outs automatically. If you’re managing manually, create a dedicated "Email Opt-Out" list.

Record the date of the request, the email address, and the source of the request. This documentation protects you if there's ever a question about compliance. You have a limited time to process these requests, so act quickly.

When can you still email a seller after a DNC?

Generally, once a seller has opted out of your email communications, you should not send him or her further marketing emails. However, if you have an ongoing business relationship, such as a signed contract, you can still send transactional or relationship-specific emails related to that deal. These are not considered marketing.

For example, sending closing documents or requests for information related to an active purchase agreement is permissible. The key distinction is whether the email is promoting a product or service versus facilitating an existing transaction.

Avoiding common email compliance mistakes

A common mistake is failing to provide a clear and easy-to-use opt-out link in every marketing email. This link must work for at least 30 days after the email is sent. Another error is not including your physical mailing address in the email.

Also, avoid sending emails with deceptive subject lines that might mislead the recipient. Always ensure your "From" field accurately identifies you or your company. These practices are fundamental to CAN-SPAM compliance and building trust with your leads.

Maintaining a clean email outreach list

Regularly audit your email lists to remove old, invalid, or opted-out addresses. Beyond legal compliance, a clean list improves your deliverability rates and the overall effectiveness of your email campaigns. Sending emails to disinterested parties is a waste of your resources.

Consider using email verification services periodically to prune out invalid addresses. This proactive approach ensures you're only reaching engaged sellers and maintaining a positive sender reputation. A well-maintained list reduces the likelihood of complaints and improves your outreach quality.

Questions people ask

If a seller opts out of texts, can I still email him or her?

Yes, unless he or she specifically requested to opt out of emails too. Text and email DNC rules are distinct. Always honor each request for the specific communication channel it refers to.

How long do I need to keep email opt-out records?

You should keep email opt-out records indefinitely. This documentation demonstrates your compliance and protects you from future complaints, especially if a seller changes his or her mind or later forgets the request.

What if I get an email bounce-back?

A bounce-back means the email could not be delivered. Remove that address from your active outreach list. Repeated bounces can hurt your sender reputation, making it harder for your valid emails to reach inboxes.
