Short version: If you're not satisfied with a license or plan you bought from us, contact us within 14 days and we'll issue a full refund, no questions asked.
We offer a full refund on business license, commercial license and partner plan purchases made within the last 14 days. To request a refund, email contact@mailflow.sh with your order details (your name and the email address used at checkout is sufficient).
Refunds are processed via Paddle and typically appear within 5–10 business days depending on your payment method and bank.
Refund requests after 14 days are considered on a case-by-case basis. If you've encountered a significant issue that prevents you from using the software as described, get in touch and we'll do our best to find a fair resolution.
The business license renews yearly until you cancel it. You can cancel at any time to stop future renewals, from the link in your Paddle receipt email or by emailing contact@mailflow.sh. A renewal charge can be refunded if you ask within 14 days of the renewal date.
Refunding a commercial (private modifications) license ends it. After the refund, the installation it covered is again subject to the AGPL-3.0.
MSP partner plans can be refunded if you ask within 14 days of each invoice. Business support plans and anything else agreed in writing follow the refund terms of that agreement.
Sponsorships through GitHub Sponsors or Ko-fi, including the Business sponsor tier, are paid to those platforms and follow their own refund and cancellation rules.
To request a refund or ask a question about your purchase, email contact@mailflow.sh. MailFlow is run by one person, so replies may take a few days.
This policy doesn't limit any rights you have under the law where you live. Paddle's buyer terms also apply to purchases made through Paddle.
