Sidemail review
A focused option for project inboxes, forwarding, and SMTP-based sending.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sidemail is a hosted email service for side projects that need project-specific inboxes without adopting a broader email marketing platform. It supports receiving messages at project inboxes, forwarding them to personal accounts or multiple recipients, and sending from an existing personal email account. Teams can also send using project-specific addresses and configure SMTP for inboxes. Its fit is strongest for individuals and small project teams organizing email around separate projects.
The plan structure is straightforward. The seven-day trial includes one project, unlimited inboxes, and no credit card requirement. Starter keeps one project and unlimited inboxes, with 2,000 emails per month. Personal adds unlimited projects and retains unlimited inboxes, with 8,000 emails per month. Sidemail also describes an 8,000-email soft limit and a 16,000-email hard limit for Personal. This makes the choice mainly about project count and monthly sending volume rather than a wide set of service tiers.
Sidemail’s main strength is its narrow workflow: receive project email, route it elsewhere, and send through project addresses or SMTP. Forwarding to multiple recipients or external services gives small teams practical routing options, while the web platform keeps the product focused. The trade-off is equally clear: Sidemail is intended for side-project email rather than mass-marketing email, and its listed delivery method centers on SMTP. Choose it when project inboxes and forwarding are the priority; choose another category option when you need a broader transactional email platform or marketing-oriented sending capabilities.
