How to Verify a Sending Domain
Who is this for?
If you send email through CDM+ you must verify your sending domain to ensure deliverability.
Per the requirements set forth by our SMTP provider, SMTP2GO, verifying your sending domain is required to ensure your emails are delivered successfully. Read more about how verifying a sending domain adds SPF and DKIM verification to emails sent from your domain on our provider's website: https://www.smtp2go.com/blog/ask-add-sender-domain/
Verifying a sending domain has two steps:
Configure your DNS provider with the verification settings
Contact CDM+ Support to confirm your verification settings are valid
What is a sending domain?
The sending domain is the part of your sending (from) email address following the at-symbol. For example, the sending domain for the email noreply@suran.com is suran.com.
You provide your sending domain when requesting SMTP hosting in CDM+.
You must have ownership of your sending domains to verify them. Shared domains like comcast.net or outlook.com cannot be use to send email from CDM+.
You can register a custom domain and configure email to forward to your provider of choice. A variety of low-cost domain registrars are available online.
Step 1: Configure Verification Settings
You will need access to configure the DNS records for your domain. Often, but not always, the company providing your web and/or email hosting also administers your DNS records. CDM+ Support may be able to identify your provider and will include this information with the verification settings.
Our SMTP provider, SMTP2GO, has a useful set of guides for how to configure DNS for a number of providers.
Follow the guide specific to your provider or otherwise configure your DNS with the following records:
Type | Hostname | Value |
|---|---|---|
CNAME | em265141 | |
CNAME | s265141._domainkey | |
CNAME | link |
Suran does not have any access to or oversight of your sending domain and related records. If you are having trouble configuring these records, we recommend contacting your DNS provider’s support for assistance.
Step 2: Confirm Verification Settings
Once you’ve updated your DNS with the settings above, reply to CDM+ Support and ask for your verification settings to be confirmed. We'll confirm that your domain appears verified with SMTP2GO or let you know which of these DNS entries isn’t quite right.
Once you've confirmed your settings you can rest easy knowing your emails will be successfully delivered.
