A HubSpot export is CRM data, so each row carries deal associations, lifecycle stage, form submissions and whatever sales typed into a note. The email address is one column among hundreds and the record belongs to several teams at once.
Getting the addresses out of HubSpot
Contacts, filter to the list you want, then Export with the email property selected. HubSpot emails the file.
Before promoting anyone to a marketing contact. That designation is the billing event and the sending event at the same time, so checking beforehand is the only moment where the result changes both.
What HubSpot does with the file you bring back
The import rules decide what a re-import actually changes, which is worth knowing before you upload.
The short version
- HubSpot deduplicates on email address by default and updates the existing contact, so re-importing a verified file enriches rather than duplicates.
- A hard-bounced contact stays blocked after an import. Clearing it is a deliberate action, and doing it in bulk is rarely a good idea.
- Marketing contact status is the billing lever. Import as non-marketing and promote deliberately.
- Custom properties import cleanly, so the verification verdict and its date can live on the record.
The mistake to avoid
Some addresses come back unresolved, and that is a fact about the receiving server rather than a gap in the check. We label those and never bill for them. What that means, and why roughly 28% of business addresses land there, is set out on our page about catch-all domains.
How to remove bounced emails from HubSpot
Start with a contact list, not a campaign report. Filter on the property that records marketing email bounces and add Original source as a column. You now see every hard-bounced contact in the portal and where each one came from.
Next, decide what removal means for your team. A bounced contact already can't get marketing email. Set it to non-marketing and it stops counting toward your marketing contact tier, while the deals, notes and call history stay on the record for sales.
Delete only the contacts nobody will miss: form spam, test entries and bot signups with no deal attached. Deleting a contact that sales has worked removes the history they'll want the next time that company comes back.
2,400 bounced contacts in a 30,000-contact portal
Say your portal holds 30,000 contacts, 18,000 of them marketing contacts, and the bounced list shows 2,400. Grouped by source, 1,500 came from one trade-show import and 600 from a gated ebook form. The rest are scattered decay.
Switch all 2,400 to non-marketing. Then look at the rest of that trade-show import and the ebook signups that haven't bounced yet, since they came through the same door. Export them and the remaining marketing contacts, 15,600 in all, and run the file through ZapBounce. Two 10,000 packs cover it for $50, and results that come back unknown aren't charged.
Import the verdict and the check date as contact properties. An active list that holds invalid results out of marketing status keeps the tier honest, and sales can still see the record.
Questions people ask
Where do I verify in a HubSpot workflow?
Export the contacts you intend to designate as marketing, check them, and import the verdict back as a property before promoting them. That order keeps the bill and the reputation honest.
Should role addresses be removed from a B2B list?
Not automatically. info@ and sales@ are frequently the right contact at a small company. Flag them, segment them, and write to them differently rather than deleting them.
How do catch-all domains affect a B2B list in HubSpot?
Heavily. Around 28% of addresses in a 10,000-email B2B benchmark sat on catch-all domains, and no verifier can confirm those mailboxes. Segment them rather than treating them as valid or deleting them.
How do I remove bounced emails from HubSpot?
Build a contact list filtered on marketing email bounces, then set those contacts to non-marketing. That removes them from your billed marketing contacts and keeps their CRM history. Delete only spam and test records.
