ZeroBounce

Check whether an email address is real and safe to send to before you ever hit send, so your outreach lands in inboxes instead of bouncing, all inside Deep Research.

How it works

Connect your ZeroBounce key once in settings, then open SalesGPT and turn on Deep Research. Just ask in plain language to check or clean up email addresses, and Deep Research reaches for ZeroBounce automatically whenever a request depends on knowing if an email is valid and deliverable. You never touch a setting mid-chat.

What you can ask it to do

Confirm an email is real before you send

→“Is maria.gonzalez@stripe.com a valid, deliverable address?”

→“Check whether this email actually exists before I reach out.”

Clean a list before a campaign

→“Run these 40 addresses and tell me which ones are safe to send to.”

→“Which emails on this list will bounce if I email them today?”

Protect your sender reputation

→“Flag any risky or undeliverable addresses in this batch before I add them to my sequence.”

→“Filter out the invalid emails from these leads so I only keep the good ones.”

Verify as a final step before adding to a list

→“Before I save these contacts to my prospect list, verify every email is deliverable.”

→“Double-check this email is valid before I add David Chen to my outreach list.”

Connect your key

Grab your API key from your ZeroBounce dashboard.

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

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

Cost

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