HubSpot

Connect HubSpot with emailcheckerr to verify every email address before it hits your campaigns. CRM platform for marketing, sales, content, and customer service. Pair it with our SMTP-grade verification to keep your sender reputation healthy, drive higher open rates, and protect your inbox placement.

Whether you import lists from HubSpot for a one-off cleanup or pipe new sign-ups through emailcheckerr in real time, you get the same disposable / role / accept-all detection, deep MX validation, and quality scoring used by enterprise teams — at a fraction of the cost.

How it works

Export your contacts

In HubSpot, export the segment or list you want to verify as a CSV.

Verify with emailcheckerr

Upload the CSV to emailcheckerr — bulk verification typically completes within minutes. You'll see deliverable, risky, and undeliverable counts plus our quality score.

Re-import the clean list

Download the cleaned CSV and re-import to HubSpot, or use Zapier / Make to push only deliverable contacts back into your tags / lists / pipelines.
