Rebump

Rebump is a Gmail extension that sends follow-up emails for you. When you send an email, you tick a box, and Rebump sends polite reminders, which it calls bumps, until the recipient replies.

It solves one small but costly problem: emails that get buried and never answered because nobody followed up.

Who is Rebump for?

Rebump suits anyone who sends many one-to-one emails from Gmail and needs answers: salespeople chasing leads, recruiters, real estate and travel agents, consultants and freelancers. It works from your normal inbox, so there are no campaigns or contact lists to manage.

It is not a cold email platform. If you send outreach to hundreds of prospects at once, with sender warm-up and multichannel steps, a sales engagement tool fits better.

How does Rebump work?

You install the Chrome extension and connect your Google account. In Rebump you create a follow-up sequence: the text of each bump and how many days apart they go out. When you write an email in Gmail, you pick a sequence and send. If the person replies, the bumps stop.

What are Rebump's main features?

Automatic follow-ups

Bumps are sent from your own account, so they look like you wrote them by hand. You choose the intervals and the days and times they go out. The basic plan allows up to 4 bumps per message and the higher plans up to 10.

Personalization and sequences

Variables add the recipient's name, company or other details to each bump. You can create several sequences, for example one for proposals and one for invoices. For ideas, read our tips on cold email templates that convert.

Tracking

A dashboard shows which emails are still being bumped, and digest emails summarize activity daily, weekly or monthly. Unlimited Plus adds open tracking and Premium adds link tracking.

Premium extras

The Premium plan adds an AI bump generator, file attachments on bumps, conditional bumping, a Zapier integration and an API.

What do users say about Rebump?

Rebump is rated 4.9 out of 5 on G2 from 55 reviews and 4.7 on Capterra UK from 7 reviews at the time of checking, though most reviews are several years old. Capterra reviewers praise how simple it is to set up, that it works inside Gmail and the time it saves on manual follow-up.

The complaints are that it only works with Gmail and Google Workspace, and that some users wanted branching sequences, for example a different follow-up when someone opens or clicks. The Premium plan now offers conditional bumping.

When should you choose an alternative?

• You want a broader sales tool inside Gmail. Compare Mixmax.
• You want a CRM that lives in Gmail. Look at Streak.
• You run cold email campaigns at volume. Use a tool such as lemlist or Woodpecker.
