Allegrow

Check whether an email address is safe to send to, resolve tricky catch-all mailboxes, flag spam-trap and abuse risk, and pin down a contact's primary email, all inside Deep Research.

How it works

Connect your Allegrow key once in settings, then open SalesGPT and turn on Deep Research. From there you just ask in plain language, and Deep Research reaches for Allegrow automatically whenever a request needs an email verified, a catch-all domain resolved, or a spam-trap risk checked. You never have to touch a setting mid-chat.

What you can ask it to do

Know which emails are safe to send to

“Verify these 40 addresses before I load them into the Acme outbound sequence.”
“Is jordan.reyes@northwind.io actually a valid, deliverable mailbox?”

Get straight answers on catch-all domains

“This domain is catch-all so my normal tool says 'unknown' — can you tell me if maria.lopez@datastride.com is a real inbox?”
“Sort my Salesforce list into real mailboxes vs catch-all guesses before I send.”

Avoid spam traps and abuse risk

“Flag any spam-trap or high-risk addresses in this list before it hits my campaign.”
“Is contact@rivergroup.co safe to email or does it look like a trap?”

Send to the address that actually gets opened

“Priya has three emails on file — which one is her primary mailbox to reach her at?”
“For each contact here, tell me the best primary email to use for outreach.”

Connect your key

1

Grab your API key from your Allegrow dashboard.

2

Open Settings, Provider Keys in Fuse, find Allegrow, and paste it in.

3

That is it. Deep Research starts using Allegrow on your next request. Fuse encrypts the key and never exposes it to the agent.

Cost

Allegrow runs on your own key, so it spends your Allegrow credits, not Fuse credits.
