A/B Testing E-mail Subscriptions

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.
