What verification does to this list

• Every address comes back valid, risky or invalid, so the campaign goes to a list you have checked rather than one that has sat in the CRM since the contact was created.
• Contacts whose mailbox no longer exists come back invalid. Set them aside or mark them in HubSpot before the send rather than finding them as bounces after it.
• Unsubscribed contacts are in the export unless you filter them out first. Verification does not know who opted out, so filter before you export.
• The cleaned files keep every column from the export, so if you export the record ID with it, they import back onto the same contacts.

How long 100,000 emails take

• We run about 13,000 mailbox checks a day today, shared by all customers. At today's shared pace, 100,000 checks in one list take about 8 days to finish. The list queues and its card shows the ETA; nothing is cut off.
• Check capacity is shared by all customers: list jobs run at up to about 60 addresses a minute while the day's capacity lasts, so a very large list queues rather than failing and can take days.
• Bad syntax, dead domains and disposable addresses come back at once, and results confirmed in the last 14 days return instantly, so a list you checked recently finishes sooner. Each job card shows an estimated finish time.

What you get back

Valid

The recipient's mail server confirmed the mailbox exists.

Risky

The domain works but the mailbox could not be confirmed, usually a catch-all domain that accepts every address. Anything unconfirmed is reported as risky, never as valid.

Invalid

The server confirmed the mailbox does not exist, or the syntax is broken, the domain has no mail server, or the domain is a known disposable provider.

Results download as separate files for valid, risky and invalid. The email column is found by its header or its contents, every other column in your file is kept, and the cleaned files come back with your original columns, so they import straight back into your sending tool.

Common questions

How do I export my contacts from HubSpot?

In HubSpot, go to CRM > Contacts. Open the view you want to export, such as All contacts. Click Export in the top right of the table. Choose CSV as the file format, name the export and click Export. Download the file from the link HubSpot emails you. HubSpot zips CSV files over 2 MB, so unzip it before dropping it here. Unsubscribed contacts are included unless you filter them out first. These steps follow HubSpot's own help article.

How much does it cost to clean a HubSpot list of 100,000?

$39 on SimpleVerifier (one month of Pro), about $0.39 per 1,000. Duplicates and addresses we cannot check are not counted, so the real number is usually lower than the row count.

How long does a list of 100,000 take?

About 8 days at today's shared pace of about 13,000 mailbox checks a day, shared by all customers. The list queues rather than failing, the job card shows an estimated finish time, and nothing is cut off.

Can I upload all 100,000 in one file?

Yes. Uploads take up to 100,000 rows in one CSV, and the email column is found automatically.

Does verification tell me who agreed to be emailed?

Verification tells you whether a mailbox can receive mail. It does not tell you whether the person agreed to hear from you, so check consent before you mail anyone, whatever the result.

Can I try it before paying?

Yes: the first 100 email checks are free with a Google sign-in and no card, on the same SMTP mailbox check the paid plans run. Upload a sample of the export first, then pick the plan or pack that fits.
