Welcome email subject lines.

Welcome subject lines work when they confirm the sign-up, set a friendly tone and promise something useful inside, because the new subscriber is at peak attention and expects to hear from you right away.

A welcome email lands while the subscriber is still thinking about your brand. Expectations are high and the relationship is brand new, so the subject line should feel warm, clear and recognisably human rather than promotional.

It sends immediately after sign-up and often leads a short series. The first message confirms what they signed up for, the next tells your story, and later ones guide them to a first purchase.

30 welcome subject lines, and why they work.
