Mailit 11. Full email workflows for FileMaker —updated for FileMaker 2026.
Mailit 11 is an advanced email plug-in for FileMaker® custom apps—updated for FileMaker 2026.
Send, receive, and manage email via SMTP, POP3, IMAP, Gmail REST API, and Microsoft Graph API, with optional sending via AWS SES. Mailit supports OAuth 2.0 workflows (Google & Microsoft), background processing (including FileMaker Server), HTML email editing, and attachments.
For security, Mailit includes email encryption and digital signatures (PGP / S/MIME) for both sending and receiving. Mailit 11 also improves stability and speed with optimized message downloading and MIME processing, reduced memory usage and better diagnostics via a REST/IMAP session transcript. See the feature list here.

Free, adoptable FileMaker® email apps
Mailit 11 includes free, adoptable FileMaker® email apps to kickstart your implementation — powerful Personal Mail app, apps for sending and receiving, HTML workflows, background processing, security features, and more...
NEW: Gmail REST API
Mailit 11 adds REST support for Gmail via the Gmail API — while keeping the familiar Mailit workflow. Connect using Emai_Connect with gmailRest and continue working with folders/labels, message loading, moving/deleting, and server-side processing.
Email signing and encrypting
Encrypt and sign emails to reduce interception and spoofing. Mailit supports widely adopted standards like PGP and S/MIME to encrypt emails and attachments using the recipient’s public key—so only recipients with the matching private key can decrypt them. You can also digitally sign messages to prove authenticity and help recipients verify the sender and detect tampering.
ENHANCED: IMAP functions
Mailit supports advanced IMAP folder management and search — create, delete, rename folders, and search by criteria like from, since, and unread. Mailit 11 adds performance improvements for message download and processing (including server-side scripts) and optimized memory usage for better stability.
Mailit lets you build professional email workflows directly inside your FileMaker® app — from composing and sending to receiving and processing replies.
Send rich HTML emails using built-in editors that integrate via FileMaker® Web Viewer. Create branded templates, personalize content, include attachments, and embed images for professional layouts.
Mailit also supports inbound email workflows: receive emails directly into FileMaker® and manage follow-ups, ticket replies, and mailbox processes inside your solution.
Run mailings and processing in the background (including FileMaker Server) to keep your app responsive.
Mailit supports secure SMTP connections, including servers that require modern TLS such as TLS 1.3.
New in Mailit 11: REST support for modern providers — Gmail REST API and Microsoft Graph API — while preserving the familiar Mailit workflow.
Mailit 11 also improves performance for message downloading and processing and optimizes memory usage for better stability with large mailboxes and server-side scripts.
As an alternative to SMTP, Mailit lets you relay personalized emails via Amazon SES (AWS SES) for high-volume sending.
More secure: OAuth 2.0, SSL, TLS 1.3
Mailit supports OAuth 2.0 and secure connections with modern TLS (including TLS 1.3 where required), plus advanced SMTP authentication and SSL. Setup guides for Google and Microsoft are included.
