The “Double-Opt-in” in Email Marketing
Posted: Thu Mar 27, 2025 9:51 am
Cold emailing with DOI (Double-Opt-in) ensures that your rich people database reach your customers’ inboxes, which is the ultimate goal of all outreach efforts. Adding DOI provides an extra layer of assurance that your contacts actually want to hear from you.
To ensure that recipients are fully opted in to receiving future marketing emails, cold emailers are required to provide a clear and visually appealing opt-in feature for them to click. This not only ensures recipient consent, but also increases engagement when paired with added value such as discounts or special offers. Proactive measures like this can help drive greater engagement in campaigns.
The easiest way to ask for consent to receive further communications is to use a professional email platform that offers double opt-in as a feature (we recommend Mailsenpai: here is our agreement , here are the reasons to choose it and here is the Mailsenpai website ). However, if you are sending a cold email in a one-to-one way (i.e. without a platform) you can also ask for an explicit response from the person you are emailing: a simple sentence like “Can I send you more information?” can be enough to start a conversation and get their permission. Asking permission is a great way to build rapport and attract the attention of potential customers.
This marketing effort is an investment in your relationship with your reader, in fact this process is only required for your first email: once you have obtained consent, you are ready to start the conversation!
