Email Clients
Send office messages via secure infrastructure
This section contains instructions for configuring desktop email clients such as Outlook or Thunderbird to send messages using MessageFlow SMTP servers.
Why configure your email client?
Even if you use an email program for manual correspondence, routing your dispatches through MessageFlow provides advantages over a standard hosting account:
High deliverability: Use our high-reputation infrastructure to significantly increase the chances of your invoices and business messages reaching the Inbox instead of the SPAM folder.
Tracking: Access the status of sent messages in the MessageFlow dashboard according to the data retention period available in your plan.
Security: Benefit from full transmission encryption via TLS and SSL.
Quick configuration (Universal parameters)
Use the following data if you know how to configure an account in your program. These settings are common to all email clients:
Parameter
Value
Outgoing Server (SMTP)
smtp.messageflow.com
Port (Recommended)
587 (Encryption: STARTTLS / TLS)
Port (Alternative)
465 (Encryption: SSL)
Username
Your SMTP login (e.g., 1.accountname.smtp)
Password
Your SMTP password
Where to find the password?
The login and password for the SMTP server differ from your MessageFlow dashboard login credentials. Create them in the Email API > Settings > SMTP Accounts section.
