Welcome Email

A welcome email is the first message a new subscriber or customer receives after signing up. It sets the tone for the relationship and consistently earns some of the highest engagement of any email.

Also known as: welcome series, onboarding email

You only get one first impression, and the welcome email is it. Sent right after someone joins your list, it arrives when interest and expectation are at their peak — which is why welcome emails post standout open and click rates.

What should a welcome email include?

Thank the subscriber, set expectations for what they'll receive, deliver any promised incentive (like a discount code), and give one clear next step. Many brands use a short welcome series rather than a single email.

Why do welcome emails matter?

They convert new interest into action, reinforce your brand, and establish sending patterns that help deliverability. A strong welcome flow often drives meaningful first-purchase revenue.

Single email or series?

A welcome series (typically 2–4 emails) usually outperforms a lone welcome email by telling your story, sharing bestsellers, and building toward a first purchase.
