Mail Shiba is a straightforward email delivery service for businesses that want to receive messages from their website contact forms without setting up or managing their own email server. Subscribers use an account provided by Mail Shiba to send form submissions to their own email address, with messages delivered by Mail Shiba on their behalf. The service emphasizes simple pricing and a flexible, good-faith approach rather than strict quotas. Customers can send the volume they need, provided their use does not overwhelm the servers; if it does, Mail Shiba says it will get in touch to discuss a suitable arrangement.

The Light Plan costs £8 per month and is intended for most small businesses, including those sending a few hundred emails on typical days and occasionally a couple of thousand. The Heavy Plan costs £40 per month and provides a dedicated, high-performance server setup for customers with greater email volumes.
