Welcome emails that
turn signups into users
The moment someone signs up is when they're most engaged. A great welcome email converts that interest into an activated user who sticks around.
Why this matters
Users who receive a welcome email within seconds of signing up show significantly higher activation and retention rates. Timing is everything.
