Why should agencies verify client lists?
When a client's campaign bounces, it is the agency's results that suffer. New clients often arrive with years-old lists, imports from several tools and a domain nobody has checked.
Cleaning the list and checking the domain before the first send sets a baseline you can report on, and keeps the client's sending reputation safe.

How do you onboard a client's email list?
Verify and report
Counts per verdict show how healthy the list is.
Audit the domain
Check SPF, DKIM and DMARC and hand over the records to add.
Set a monitor
Re-check the connected list on a schedule from then on.

What do agencies use most?
- Bulk verification and clean exports for each campaign.
- Monitors on clients' connected email tools, with optional tagging of bad addresses.
- Domain audits and mail server tests for new and existing clients.
- The API, for agencies that verify inside their own forms or tools.

How is it billed for agencies?

Mailcleaner capabilities that matter to marketing agencies
List cleaning
Clean an email list in one upload: counts per verdict, a clean CSV or XLSX export, and a suppression list so bad addresses don't creep back in.
Monitors
Re-verify a connected Mailchimp, Brevo, HubSpot or other list daily, weekly, monthly or quarterly, and optionally tag bad addresses back in the tool.
Domain checks
Check your domain's SPF, DKIM, DMARC, BIMI, MTA-STS and TLS-RPT records, see Gmail and Yahoo requirements, get DNS fixes and test your mail server.
