Using Mailflow
By creating an account you agree to use Mailflow's sending infrastructure only for lawful email you have the right to send, and to comply with applicable anti-spam and data-protection law in the jurisdictions you send to.
Credits & billing
Credit bundles are one-time purchases, not a recurring subscription. Credits do not expire and are drawn down as messages are delivered through your organization's account.
Suspension
Accounts found sending unsolicited or abusive email may be suspended while we investigate, in order to protect deliverability for every organization on shared infrastructure.
