Why Meisa exists

Every email change used to be an engineering ticket.

Meisa was built by a SaaS team that hardcoded its emails and waited a sprint for every copy change while trials went cold. Now the people who write the emails ship them.

Triggers and sequences

Your app says what happened. Meisa sends the right email.

Send an event from your product with one API call. The right sequence starts, waits, checks what the user did and sends the right next email.

A welcome that goes out the second someone signs up
A nudge when a trial goes quiet on day 2
A win-back when a customer stops logging in
Receipts, password resets and alerts through the same pipe

Questions founders ask.

Who is Meisa for?

SaaS founders and small growth teams who want onboarding, trial, win-back and product update emails running on their own, without an engineering ticket for every change. It also runs newsletters and one-off broadcasts.

How does Meisa keep my emails out of spam?

You send from your own verified domain, Meisa writes natural variations of the sentences you pick so no two recipients get an identical email, Warm Send spreads big sends into safe batches, and dead addresses are suppressed automatically.

How do emails react to what users do in my app?

Your app sends events to Meisa (for example signed_up or data_not_connected) with one API call. Sequences and triggers start, wait, branch and stop based on those events.

Can I use my own Amazon SES?

Yes. Connect Amazon SES, SendGrid, Mailgun or any SMTP and pay them directly at cost, or let Meisa send for you and be live in about two minutes. You can switch later and keep everything.

When do I pay?

Every plan starts with a 7-day free trial. Add a card to start it and you are not charged until the trial ends. Every plan also has a 14-day money-back guarantee.
