Custom Domain Email Forwarding
Other email services advertise as open-source, but they do not release the source code to their back-end. The back-end is the most sensitive part of an email provider. It is also important to use 100% open-source because it builds trust and allows anyone to contribute and independently audit.

Frequently Asked Questions
Browse commonly asked questions and answers about pricing below.
Do you offer unlimited domains for one price?
Yes. Regardless of which plan you are on, you will pay only one monthly rate – which covers all of your domains.
Do you accept one-time payments and subscriptions?
Yes. We accept both one-time payments or monthly, quarterly, and yearly subscriptions.
Do you offer a money-back guarantee?
Yes. We offer a 30 day money-back guarantee – with no questions asked.
Can I configure Spam Scanner settings?
Yes. You can toggle filters for adult-related content, phishing, executables, and viruses from Settings.
Do you store SMTP logs or write to disk?
No. We have a Privacy Policy of not storing SMTP logs, metadata, nor emails (with the exception of errors). You will find that every other email forwarder stores SMTP logs and writes your emails to disk storage... usually on unencrypted databases and without SOC 2 Type 2 compliance. This common practice is a huge security risk for you, and is another reason why we built our service. Our expertise allowed us to build our own custom solution that uses memory-based streams, and is lightning fast and privacy-focused.
We don't track you like other services do.
