Core9 Email review
A capable free starting point for small teams that need custom-domain email.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Core9 Email provides hosted email on custom domains for individuals and small businesses. It combines browser-based webmail with IMAP access, so teams can manage messages in the web interface or connect standard clients such as Outlook, Apple Mail, Thunderbird and Gmail. Its feature set also covers spam and virus filtering, automatic DKIM and SPF configuration, mailbox migration, and an administrative console for mailboxes, domains and permissions. The Free plan suits small web-only teams that want a branded email address without a recurring charge.
The pricing structure starts with the Free plan, which includes a custom domain, full webmail, email support and mailbox migration. Professional costs BRL 19.90 per month and adds priority support, advanced webmail, two-factor authentication and automatic backup alongside the core email features. Enterprise costs BRL 39.90 per month and includes priority support, every advanced feature, a custom domain and mailbox migration. Annual billing saves 10%, while the published paid plans are presented with monthly prices. This makes the Free tier the clearest entry point, while Professional is the more suitable choice for organizations that need stronger account protection and backup coverage.
Core9 Email fits teams that want standard email-client compatibility without assembling separate migration, filtering, domain-record and administration tools. IMAP support broadens client choice, while the web platform keeps mailbox and permission management centralized. The trade-off is that the strongest operational additions are concentrated in paid tiers: priority support, advanced webmail, two-factor authentication and automatic backup are associated with Professional, and Enterprise is the higher-cost route to every advanced feature. Choose Core9 Email for straightforward custom-domain hosting and a free starting tier; consider another service if your priority is a broader application ecosystem or a lower paid entry point.
