Rebump - Email Follow Up vs. Courier

Automated Email Follow-up Made Easy! Rebump sends multiple follow-up email messages to your recipients for you. These automated emails are customized to appear as if you sent the follow up yourself. You can track and analyze all of your follow-up emails with your Rebump account. Now includes email tracking. For Gmail or G Suite (Google Apps).

Courier is notification infrastructure for customer messaging, built for humans and AI agents. It sits between your app and every channel you send on: email, SMS, push, in-app inbox, chat, and webhooks. You send one request, and Courier works out where it goes, what it looks like, and whether the user wanted it at all. Teams use it for the messages a product has to send: onboarding, alerts, receipts, reminders, and account notices. You keep the providers you already pay for. Courier is the layer above them.
