A call to action (CTA) is what an email asks the reader to do next: reply, book a call, look at something. In cold email it's usually the last line, and it decides whether a reader who's interested actually responds.
Small asks work best
Someone who has never heard of you won't commit to a 30-minute demo from one email. A question that takes ten seconds to answer is much easier to reply to:
- "Is this something you're working on this quarter?"
- "Worth a quick look, or not a priority?"
- "Who handles this on your side?"
Once they reply, offer the call.
Rules of thumb
- One CTA per email. Two choices halve the replies to each.
- A question rather than a link in the first email.
- Easy to say no to: an easy "no" brings honest "yes" replies too.
- Change the ask in follow-ups instead of repeating it.
