FAQs

Do I need technical knowledge to set up Cleanmails?

No, free installation is included with every license. The Cleanmails team handles the setup on your server end-to-end, ensuring you are ready to send campaigns on day one without needing advanced technical expertise.

What server requirements does Cleanmails have?

If using the inbuilt SMTP or email validation, a Linux VPS with Port 25 open is required. For external relays and validation, Port 25 is not needed, and Cleanmails can even run locally without a VPS. A $6-$10/month VPS can handle thousands of emails daily.

Does Cleanmails truly offer unlimited usage?

Yes, Cleanmails offers truly unlimited usage with no contact, email, domain, or sender limits. The only practical limitation is your server's capacity, which is substantial on a standard VPS.

Are updates included with the one-time payment?

Yes, all future feature updates and performance patches are included free for life. There are no maintenance plans or renewal fees; updates are yours as long as you hold a license.
