> Promu paces your sending, monitors bounce, spam and reply rates per inbox and slows down before problems start, so your cold emails land in the inbox.

**Land in the inbox. Stay there.**

Promu paces your sending, watches your reputation and slows down before problems start, so your emails reach the people you wrote them for.

## Human-paced sending

Sensible daily limits and natural spacing between emails protect your reputation from day one.

## Health monitoring

Bounce, spam and reply rates are tracked per inbox, every day.

## Brakes built in

If an inbox shows warning signs, Promu reduces its volume before damage is done.

## A preflight for every campaign

Authentication, content and sending limits are checked before the first email goes out.

## Write for people, not filters

Promu flags spammy phrases and heavy links while you write, and suggests plainer alternatives.

## Works well with
