Sidemail
What Sidemail is
Sidemail provides project inboxes for side projects through a web service using SMTP. Messages sent to a project inbox can forward to one person, several people, or an external service. To send mail, users compose from their personal account and choose a Sidemail inbox, keeping the personal address private from recipients. Sidemail supplies SMTP details when an inbox is created, and says email is routed through Mailgun. The service is intended for side-project email rather than mass marketing, and is positioned for people testing ideas who do not need a full email provider for every project. It advertises unlimited projects and inboxes, while plan allowances differ. Starter costs $2 a month for one project and 2,000 emails; Personal costs $8 a month for unlimited projects and 8,000 emails. An unpaid plan is unavailable, but a 7-day trial is offered. Sending limits include an 8,000-email soft limit and 16,000-email hard limit.
