'Start your free trial' or 'Start my free trial'. The difference is a single word, and it's one of the most tested micro-decisions in email and web copy, because it's cheap to test and the effect, while usually modest, tends to be consistent in one direction.

Why first-person often wins

The widely cited explanation traces back to a well-known Unbounce case study, where changing a button from 'Start your free trial' to 'Start my free trial' lifted click-through by around 90%. The theory: first-person phrasing puts the reader inside their own decision, as if they're narrating their own action, rather than being told what to do by the brand. Second-person framing, by contrast, can read as slightly more like an instruction than a choice.

It's worth treating that specific 90% figure as a striking example from one test rather than a universal law. The direction, first-person often outperforming second-person on button copy specifically, shows up often enough in practitioner testing to be worth trying, but the size of the effect varies considerably by audience and context.

Where this doesn't apply

This is a button-copy pattern, not a whole-email rule. The body of your email should still speak directly to the reader in second person, you, your, because that's how normal conversational writing works and how trust gets built across a paragraph. The first-person shift is specifically useful at the point of action, the button itself, where the reader is about to make a small, individual decision.

TIP

Try this on your next automated flow: keep your body copy in second person throughout, then test 'Get my [thing]' against 'Get your [thing]' on the button alone. Small, isolated tests like this are exactly what A/B testing in a flow is best suited for.

Beyond first versus second person: what makes any CTA work

The person-framing choice matters less than getting the fundamentals right first. A CTA should describe the specific outcome, not a vague action: 'See Comparative Filters' tells the reader exactly what happens next, in a way 'Learn More' or 'Click Here' never will. Specificity consistently outperforms vagueness regardless of which grammatical person you choose.

One CTA, clearly stated, beats several competing ones

An email with a single, clear primary action is easier to act on than one offering three competing options. If you genuinely need a secondary action, a reply-to-this-email or a lower-commitment link, keep it visually and hierarchically secondary, so there's no ambiguity about which action the email actually wants the reader to take.

Testing it properly

Because the effect of person-framing tends to be modest and audience-dependent, this is a genuinely good candidate for your own A/B testing rather than something to apply on faith from someone else's case study. Test it in isolation, keep the rest of the email identical, and let your own list's behaviour settle the question for your specific audience.

Frequently Asked Questions

Is first-person CTA copy always better than second-person?

Not always, but it wins often enough in practitioner testing to be worth trying. The size of the effect varies by audience, so it's a good candidate for your own testing rather than a rule to apply blindly.

Should my whole email be written in first person?

No. Keep the body of the email in second person, speaking directly to the reader as 'you'. The first-person shift is specifically useful on the button itself, at the point of decision.

What matters more than first versus second person?

Specificity. A CTA that names the actual outcome, like 'See Comparative Filters', consistently outperforms a vague one like 'Learn More', regardless of grammatical person.

How many CTAs should one email have? One clear primary action. A secondary, lower-commitment action can work if it's visually and hierarchically secondary, but competing equal-weight CTAs tend to reduce overall action.
