DeoMail vs Shutbox
Both stand on private email services. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Web
Choose DeoMail if you need custom-domain email with forwarding, automation, message controls, or an API. Its free plan includes a mailbox, domain, and unlimited incoming mail. Look elsewhere for bulk marketing campaigns or if the 100-message daily starting limit does not suit your sending needs.

Shutbox combines a feature-rich web inbox with device-side encryption for mail between its own accounts. Before choosing it, consider the beta status and the different encryption and metadata treatment for mail sent to other providers.
