Does checking an address send any email to it?

No. Validation is a lookup against Mails.so, not a delivery, so a check never lands in the recipient's inbox or alerts them in any way.

Can Hubi flag risky addresses, not just invalid ones?

Yes. Mails.so typically returns a status that separates deliverable addresses from risky ones, such as disposable or catch-all domains, and from clearly invalid ones, and Hubi relays that distinction.

Can Hubi validate a large list in one go?

You can give Hubi a batch and it validates each address through Mails.so. Very large lists may run into your plan's rate or volume limits, in which case Hubi processes them in chunks.

Does Hubi keep a copy of the addresses I check?

Hubi passes addresses to Mails.so to get a result and returns it to you. It does not retain its own separate store of your list beyond the conversation unless you ask it to write the results somewhere you control.

All Integrations

Mails.so

Communication Email

Sending to a fake or mistyped address quietly drags down your deliverability and wastes part of every campaign. Hubi runs an address through Mails.so before you send, tells you whether it is valid, risky, or undeliverable, and checks a whole pasted list in one pass so bad addresses never make it onto your send.
