BillionVerifyAggregate
Aggregate & update documentation from Slack, Teams & GitHub with Claude Sonnet 4.5
Pull contacts, verify each address with BillionVerify, and continue to Aggregate — only deliverable addresses get through.
Why verify before the send
Sending to invalid, risky, catch-all, or disposable addresses spikes your bounce rate and erodes sender reputation. A verification gate before the Aggregate step removes that risk automatically — only deliverable addresses continue, the rest are flagged.
The workflow
BillionVerify — verification sits right before the send.

}When to use this
- Cleaning a list before a Aggregate send or sync.
- Protecting Aggregate deliverability and sender reputation.
- Keeping bounce rates low so your sending is never throttled.
FAQ
Why verify before sending in Aggregate?
Verifying first keeps your bounce rate low, which protects your sender reputation and your results.
How do I import this workflow?
