Mimestream is free for a limited time during beta.

Mimestream is dedicated to building high-quality software, without compromising your privacy. We do not monetize your data for advertising or market research purposes.

In order to build a sustainable business that can continue to innovate our products, while focusing on security, reliability, and performance, we will charge for Mimestream.

Pricing has not yet been determined, and will be announced in the future.


Why will this app cost money?

Mimestream's core business is developing high quality e-mail software, and doing this requires revenue. Instead of monetizing your e-mail data for advertising or market research purposes, we take a firm stance on privacy, and charge for our software.

Will you offer an enterprise site license?

Yes! A site license is a great way to offer Mimestream to all of your employees and boost their productivity, while being confident in the secure handling of your organization's data.

Please contact us with how many seats you'd like, and we'll get back to you as soon as Mimestream is available for site license purchase (after reaching 1.0)! In addition, if you have any special requirements or wishlist items, we'd love to hear from you!
