Perfecting your email CTA

All the content pieces of your email copy are important. But when your recipient reaches the CTA, this is the defining moment of whether or not they take the next step or become closer to converting.

It pays to give your CTA some special attention.

The CTA section of our new guide includes advice and best practice tips on:

  • Placement – where should you put it and how many should you really have?
  • Copy – time to get creative. We have some examples to inspire you and some tips to save you time.
  • Design – button, plain text, or a combination of both? All the options make sense; we help you decide which design is best for your email.

Now is the perfect time start crafting your best CTAs.


We decided to combine A/B testing and CTA best practice because when completed together you can 1) measure your email performance and 2) provide persuasive and valuable email content. But if you’re only interested in one of the topics, you can easily navigate around to the content you want.

Head on over to the guide now to get all the details to ensure your testing strategies and CTAs are engaging and converting your recipients.
