📧 Multiple Alias Types

Domain Aliases: Get your username across all 30+ included domains with your account. Toggle them on or off as needed, each also has its own catch-all subdomain.

Masked Aliases: Create aliases with any name you choose across 30+ domains. Toggle them on or off as needed, each with its own catch-all subdomain.

Auto-Expiring Aliases: Addresses that self-destruct on a specific date (format: YYYYMMDD@domain). Perfect for temporary signups.

📝 Integrated Calendar, Tasks & Notes

Calendar: Create multiple calendars with full event management, invitations, reminders, and recurring events. Automatically generate birthday calendars from your contacts. Import national holidays for over 80 different countries. Convert emails directly into calendar events. Import and export standard iCalendar (ICS) files. Live sync with your phone's calendar, tablet, or other.

Tasks: Create task lists with due dates, priorities, and filtering. Convert emails directly into tasks. Import and export ICS files. Live sync with phone, tablet, or other.

Notes: Store private notes right alongside your email. Create notes in Markdown, HTML, or plain text. Upload and store images and PDFs. Search instantly and send any note as an email attachment with one click.

🚫 Powerful SMTP-level Blocking System

Alias Control: Disable any address instantly - if an alias gets compromised or spammed, turn it off and senders get "user unknown." Use blacklist mode (default) or switch to whitelist where only approved senders can reach you.

Sender Blocking: Block specific senders, entire domains, or whole domain endings (like .xyz or country codes).

Disabled addresses and blocked mail look exactly like a non-existant account to senders, causing them to remove you from their list.

📅 Private Calendar, Task & Contact Sync

Connect your phone, tablet, or computer's built-in calendar and contacts apps directly to CodaMail. Add an event on your phone and it appears in webmail. Update a contact in webmail and it syncs to all your devices. Full two-way sync using standard CalDAV and CardDAV protocols that work with iOS, Android, macOS, Windows, Thunderbird, and more. Unlike other services, we generate separate logins for each device or person you share with - none of which reveal your account name or identity. Share a calendar with a colleague without them ever knowing your username. Control exactly what each person can do (read only, create, update, delete, etc.), set expiration dates, and revoke access instantly.

🌍 Block by Language

Filter email by language at the server level. Accept mail only in languages you understand, or block entire languages if you only receive spam in certain character sets. Perfect for international users or anyone tired of foreign-language spam slipping through.

🔗 Secure Link Attachments

Send encrypted files to anyone - even Gmail users who don't have encryption. Your file is encrypted on your computer before upload, then shared as a link. Only people you give the password to can download it. Get notified when someone downloads your file, and it auto-deletes after 24 hours. Perfect for securely transfering private documents.

📥 Email Hub

Pull email from your other accounts into one place and even encrypt it automatically upon retrieval. Send from those accounts too - replies appear to come from the original address, routed through the proper mail server so your messages are authenticated and don't land in spam. Use CodaMail as a secure hub for all your email without exposing your IP address.

🤖 Advanced Mail Filters

Automatically organize incoming mail with powerful filters. Sort by sender, recipient, subject, or message size. Move to folders, forward, delete, flag, set up auto-replies or vacation responses. Plus our unique auto-encrypt action - automatically encrypt specific messages as part of any message filter.

⏰ Scheduled & Delayed Send

Schedule for later: Compose now, send at any future date and time - uses your configured timezone. Perfect for birthday greetings, business hours delivery, or reminder emails. View, edit, reschedule, or delete pending messages anytime.

Undo Send: Configure a 5-30 second delay after clicking send - giving you a window to catch mistakes, add forgotten attachments, or cancel entirely. Two ways to control when your mail actually goes out.

📬 Restricted POP & IMAP

Control how email apps connect to your account with App Passwords. Create separate passwords for each device, restrict by IP address or location, limit what each can do (receive only, send only, etc.), set expiration dates, and revoke access instantly. Protects against hackers trying stolen passwords.

✉️ Auto-Reply, Forwarding & Templates

Vacation Auto-Reply: Set start and end dates, customize your message and subject, control how often to reply to the same sender, and choose what happens to mail while you're away (keep, discard, or forward).

Filter-Based Auto-Reply: Create conditional auto-replies using mail filters. Automatically respond to messages matching specific criteria like sender, subject, or recipient.

Flexible Forwarding: Forward all mail to another address, or forward a copy while keeping the original. Use filters to forward only specific messages based on sender, subject, or other conditions.

Quick Responses: Save template responses for common replies. Insert them with one click when composing to save time on repetitive messages.

🔐 Flexible Encryption

Encrypted by Default: Every email is individually encrypted with AES-256-GCM before storage - headers and all. Your mail is protected at rest without any configuration needed.

Zero-Access Option: For maximum security, generate your own PGP keys on your own hardware - we never touch key generation. Upload only your public key. We can encrypt incoming mail, but we literally cannot decrypt it. Only you can, using your own software like Thunderbird, Apple Mail, or Mailvelope.

Flexible Auto-Encrypt: Choose what gets encrypted. Auto-encrypt all mail, only specific aliases, or only messages matching certain filter criteria. Mix and match based on sensitivity.

True End-to-End: When your correspondents encrypt before sending, we're just a blob store - we never see plaintext at all. Your mail, your keys, your choice.

📝 Custom Header Control

Automatic Privacy Protection: We strip 35+ identifying headers from every outgoing message - X-Originating-IP, User-Agent, X-Mailer, and dozens more that reveal your location, software, and device. We give you full control to adjust this should you want specific headers left.

Custom Headers: Controlling headers helps protect your email client from being fingerprinted by client added headers.

Per-User Control: Add your own custom headers or remove additional ones beyond our defaults.

Works Everywhere: Header control happens at the server level, so it works regardless of whether you use Thunderbird, Apple Mail, Outlook, your phone, or our webmail.

🚫 Ad-Free & Tracking Protection

No Ads, Ever: We don't show ads, sell data, or monetize your attention. Not even ads for our services. Your inbox is yours alone.

Remote Image Blocking: Block tracking pixels and remotely hosted images that marketers use to know when you opened their email. View messages safely without triggering read confirmations.

Read Receipt Blocking: Automatically strip read receipt and delivery notification headers - senders can't demand to know when you read their mail.

No External Resources: Our entire interface loads locally - fonts, icons, scripts, and styles. No calls to Google, no CDNs, no analytics, no telemetry. Nothing phones home.

🛡️ Cryptographic Sender Verification

Every sender gets a unique visual avatar based on a cryptographic hash. If someone tries to impersonate a contact you know, their avatar will be completely different - making phishing attempts obvious at a glance. Spot email forgeries before you even read them.

⏰ Deadman Switch

Automatically send pre-written messages with or without attachments if you don't log in for a set number of days. Useful for notifying loved ones or business partners if something happens to you. Can also automatically lock or delete your account for added peace of mind. Messages and attachments are fully encrypted prior to storage.

🔒 VPN, SSH & Web Hosting
