What it does

Brevo is an email platform with an SMTP relay, so apps can send email as an address on your domain.

  • Sending the first emails you approve, from your project's own address
  • Sending threaded follow-ups until someone replies

Get set up

  1. Authenticate your domain in Brevo (DKIM and DMARC records)
  2. Create an SMTP key
  3. In Settings → Sending: host smtp-relay.brevo.com, port 587, your SMTP login and key
Open Brevo pricing

Where it goes

In the dashboard, open Settings and find the Sending (SMTP) section. Secret values are encrypted before they're saved and only their last four characters are ever shown again.

Staying free

Larvabot sends one or two emails a day per campaign by default, only inside a send window on the days you pick (weekdays by default), and only emails you've approved or let autosend schedule at your pace. Each email has an opt-out line and a List-Unsubscribe header. Brevo expects its users to follow its sending policies, so keep outreach personal and low-volume, and check their terms for your use.

How the quota guard works →

Larva tip

Any SMTP service works (Amazon SES, Mailgun, your host's mail server). Brevo is simply the most generous free one.

Larva tip

Your timezone (for example Europe/London) sets the clock for scheduled times, the send window and daily limits; blank means UTC. Send window is in hours of that timezone, for example 7-16, on each project's send days (Monday to Friday unless you pick others under Setup → Autosend): scheduling fills it, one email every few minutes.

Fallback order

For email, Larvabot tries these in order and skips any that aren't set up, are out of free quota or are busy.

  1. 1SMTP (e.g. Brevo free)
  2. 2IMAP inbox (e.g. Gmail)
