Have you ever subscribed to an e-mail newsletter and instantly received an e-mail asking you to confirm your subscription?
This is called double opt-in and it’s designed to prevent subscribers from receiving unsolicited e-mails. It also helps e-mail marketers keep their lists full of working e-mail accounts.
It’s imperative for e-mail marketers that you click the “confirm your subscription” link in the confirmation e-mail. This is the final action that adds you to their subscription list.
Smart e-mail marketers perform A/B tests on their confirmation e-mail subject lines to determine which subject gets subscribers to confirm their address.
Here are a few confirmation e-mail subject lines e-mail marketers test:
- Please confirm your e-mail address
- Confirm your e-mail address
- E-mail confirmation
- Confirm subscription to [company name]
- Response required, confirm your subscription
Recently Alex Pankratov of Bvckup performed a small A/B test for his e-mail subscribers that increased the number of completed subscriptions from 51% to 82%.
He simply changed his subject line from the generic “E-mail confirmation” to “Please confirm your e-mail address”. By making his call-to-action clearer he was able to increase his subscriber rate.
Testing your confirmation e-mail headlines is just another example of how a simple hypothesis followed up by measuring and testing can yield more conversions for your marketing campaigns.
