Can Hubi tell the difference between invalid and just risky addresses?

Yes. Mailcheck typically returns a status that distinguishes deliverable addresses from risky ones like disposable or catch-all domains and from clearly invalid ones, and Hubi relays that status in plain language.

Does Hubi send any email when it verifies an address?

No. Verification is a lookup, not a send - Mailcheck checks the address without delivering anything, so a check never lands in someone's inbox.

Can Hubi verify a large list at once?

You can hand Hubi a batch of addresses and it will check each through Mailcheck. Very large lists may be subject to your plan's rate or volume limits, in which case Hubi works through them in chunks.

Will verified addresses be stored anywhere by Hubi?

Hubi passes addresses to Mailcheck to get a result and returns that result to you. It does not keep its own separate copy of your list beyond the conversation unless you ask it to write the results somewhere you control.

All Integrations

Mailcheck

Communication Email

A bounced email hurts your sender reputation long before you notice the drop in deliverability. Hubi checks an address against Mailcheck before you send, tells you whether it is valid, risky, or undeliverable, and runs the same check across a list you paste in - so bad addresses never reach your send.
