Welcome Email Subject Lines
Welcome emails are typically among the most-opened messages you will ever send, because the subscriber just asked to hear from you. The subject line should confirm they are in the right place and point at the first useful step.

Why these work
Confirm and orient
“You're in. Here's what happens next” removes doubt and sets up the email.
Deliver the promise
If they signed up for a guide or a code, say it is inside.
Use their name once
A {first_name} merge tag feels natural in a welcome. Make sure it has a fallback.
Write your own welcome lines
Describe your email and the AI generator writes 12 options in this style, each scored.

Frequently asked questions
What should a welcome email subject line say?
Confirm the sign-up and hint at the value: “Welcome aboard, here's your guide”, “You're in: 3 steps to get started”. If you promised a discount or download, mention it.
When should I send a welcome email?
Immediately. Interest is highest in the minutes after someone signs up, and a fast welcome also confirms the address works.
Should I send one welcome email or a series?
A short series of two to four emails over the first week or two lets you introduce the brand, deliver the promised value and make a first offer without cramming it all into one message.
