IONOS Email review

IONOS sells its own email plans and also resells Microsoft 365 and Google Workspace, so a small business can buy domain and email in one place. The entry IONOS Email plan is $1.10 a month on a 3-year term, then $2 a month, for 1 account with 2 GB that can be expanded. The middle plan covers 25 accounts with 2 GB each for $2 a month on a 3-year term, then $4, which is unusually cheap for a team that needs many small mailboxes. The top plan gives each user a 50 GB account with premium virus protection and team collaboration tools for $3 a month on a 3-year term. Every IONOS Email plan includes a free custom domain, 24/7 support and a 30-day money-back guarantee, and an optional Webmail AI assistant drafts and summarizes messages. The weak points are the 2 GB mailboxes on cheaper plans and the long terms needed for the lowest prices.
