What is Email Signature Opt-In?

The marketing growth tactic of "Email Signature Opt-In" essentially transforms an often overlooked area of your email, the signature line, into an opportunity for growing your contacts or email list.

With its advent in the digital age, this tactic involves adding an intriguing call-to-action (CTA) and a link to your email signature which would motivate recipients to sign up for your content or newsletter.

Interestingly, the Email Signature Opt-In is a spin on the traditional subscription method, which exists as long as email marketing itself. In the context of conversions, this tactic is highly effective. This is because every email you send becomes a potential avenue for conversion, increasing your audience without necessitating a significant increase in efforts. By turning a routine part of communication (like your email signature) into a consistent conversion tool, you effectively put your growth on autopilot.

Examples of Email Signature Opt-In

1. An author can include a CTA in their email signature to invite recipients to download a free chapter of his or her latest book and subsequently, sign up to their newsletter.
2. A local grocery store could use this tactic to promote its weekly e-flyers, by adding a sign-up link in the signature line of all outgoing emails from their customer service team.
3. A consultancy firm could add a link to subscribe to an industry-specific report, thereby building potential leads.
4. Companies involved with charitable work or fundraising can include a link to their email newsletter in their signature line to encourage donation and participation.
5. A tech start-up could include an invitation link to their beta product trial in each team member's email signature.
