How To Send Email Using CritSend's SMTP Relay
Two easy steps to send your CritSend mail:
Step 1: Configure your mail server or mail client.Step 2: Test & send.
If instead you wish to send through CritSend using our SOAP API, see CritSend's API doc page for API info and examples.
Step 1: Configure
Basic Setup Info
Point to CritSend's SMTP relay using the following parameters:
- Server:* smtp.critsend.com
- Port: 25 or 587
- Username: [your CritSend username]
- Password: [your CritSend password]
- Encryption: Plain Text
- *Amazon Web Services customers can user our server within EC2: aws-smtp.critsend.com
- Because you are connecting to a distributed cluster, it is also a good idea to set your software or app to retry automatically if you receive a connection error, and to re-resolve the domain if you have a failed attempt.
