Allegrow is the AI email deliverability connector. This optimizes your outreach so that more of your emails reach the primary inbox, rather than the spam folder. It's become harder to reach the primary inbox, with spam filtering becoming stricter all the time. Allegrow is a specialized platform for outbound email deliverability that works by letting you connect all your GTM inboxes and contacts to our app, then analyze and improve results from one Claude connector including: email verification, spam rate monitoring, warmup, and the ability to analyze + draft emails across multiple inboxes with one user.

After connecting Allegrow to Claude, you’ll have access to the following to optimize your deliverability:

  • Email Verification: By conducting risk analysis on every contact, you steer clear of spam traps, emails that bounce, or even flag invalid catch-all emails most verifiers can’t detect.
  • Warm up Interaction Emails: After connecting your inboxes to Allegrow, we’ll provide positive signals from real corporate mailboxes to improve your sender reputation and warm up email accounts.
  • Spam rate reporting: providing a single source of truth for the exact percentage of your email traffic reaching the primary inbox vs the spam folder each day.
  • Health Score Leaderboard: See how every rep ranks against their peers for sending health to avoid risk and provide support where it’s most required.
  • Content Testing: Allows you to A/B test your emails to see which version delivers more to the primary inbox vs the spam folder.
  • DKIM, SPF, and DMARC Testing: Allegrow uses real email traffic to highlight any authentication issues hurting your deliverability and resolve them.
  • Multi-email account search: Once you have all your inboxes connected to Allegrow, you’ll be able to search across them for important messages/analysis, all from this one connector (no more missed emails or blind spots in secondary/group inboxes).
