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

Relevance and timing

Email your users actually want.

Meisa is for people who opted in. Every send is tied to what a user did, paced sensibly, and stopped the moment someone opts out.

Wording in your voice

Pick a sentence. Meisa writes natural variations in your voice, so an email reads like a note from you, not a template.

A second chance to read

One click sends a reminder with a fresh subject line to subscribers who missed the first email.

True open rate

Privacy proxies and security scanners open emails too. Meisa filters them out so you see real readers.

Most of our trial users sign up and then go quiet. Can you set up a short onboarding sequence in Meisa for new trials and turn it on?
meisa_create_sequencemeisa_add_sequence_stepmeisa_activate_sequence

Done. I created Trial onboarding with three emails and switched it on. Everyone who starts a trial from now on gets it, and they leave the sequence as soon as they upgrade.

  1. Day 0Welcome to Northwind, here is your first step
  2. Day 2Your first report takes two minutes
  3. Day 5Stuck on anything? Just reply

The first one goes out the next time someone signs up. Want me to send you a test of all three?

Yes, send me the tests

Claude connector

Or just ask Claude to do it.

Connect Meisa to Claude or Grok Bot once. Then build sequences, write broadcasts, check results and manage contacts by asking in plain English.

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 email wanted?

Meisa is for opt-in email only. You send from your own verified domain, each email is tied to what a user did so it arrives when it is relevant, big sends start with your most engaged contacts, and anyone who unsubscribes, bounces or complains is 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, that is how Meisa works. Connect Amazon SES, Postmark, Resend, SendGrid, Mailgun, Brevo, SparkPost, Mailjet or any SMTP and pay them directly at cost. Never set up SES before? Our AI guide walks you through it in the Claude browser extension.

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.
