How to add an Email Sending Domain to Insightly Marketing

Admins can add their email sending domains in Insightly Marketing to strengthen the authentication of outgoing Emails.

Have your SPF or DKIM email authentication protocols ready for this process.


Reputation - An email sender reputation is a score that an Internet Service Provider (ISP) assigns to an organization that sends email. The higher the score, the more likely an ISP will successfully deliver emails.

Senders whose content generates high rates of SPAM complaints or are excessively identified as SPAM will likely to see their Insightly Marketing Emails fail to reach their Prospect's inboxes.

IP address  - An IP address is a set of numerical instructions. Typically, an IP address will look like a string of numbers. The reputation of an IP address is based on the performance of all senders who are using the IP address.

By default, you will share an IP address with other Insightly accounts. If necessary, you can purchase a dedicated IP address through our sales team.

Domain name - The domain name functions as a link to the IP address. These links do not contain actual information themselves, but they do point to the place where information resides. 

Think of IP addresses as the actual code and the domain name as a nickname for that code.

SPF and DKIM  - SPF stands for Sender Policy Framework. DKIM stands for DomainKeys Identified Mail.

They are email authentication protocols that help ensure that the mail you send is verifiable and that it stays out of SPAM boxes. Authentication allows the owner of a domain to specify which mail servers are allowed to send emails from the domain. Learn more.

How Email Sending Domains work

An email sending domain is used to indicate who an email is from and determines whether or not an Email sent from Insightly Marketing can successfully reach your Prospects.

When an Email is registered as delivered, it means the recipient mail server has accepted the message and will then decide what to do with that message.

The recipient server will receive a request to accept the incoming Insightly Marketing Email. Once confirmed, the recipient server will become responsible for delivering the Email.

Most often, the server will either deliver the message to the intended inbox or to send it to the recipient's SPAM folder.

In rare cases, a receiving server might choose to simply drop that message. In those cases, the message will not be findable to the recipient, even if they look for it in their SPAM folder. 

IP addresses

Insightly has several pools of IP addresses for users that have not purchased their own to share with other Insightly accounts. 

When one of the shared IP pools is added to a deny list or black list, Insightly receives an automatic notification and handles the delisting request on behalf of the Insightly users. Removal time varies depending on the list.

We recommend a dedicated IP address for clients sending high volumes of email or for people who want control over the quality and reputation of mail sent from their IP address.

Customers can purchase multiple dedicated IP addresses and use a combination of them in a pool if they wish. Contact our sales team to discuss purchasing IP addresses.

How to add an Email Sending Domain

  1. Go to System Settings > Domain Management.
  2. Click Add Domain. Select Add Email Sending Domain.
  3. Enter your Email Domain. Click Generate Keys.
  4. Once the keys have been generated, add a CNAME record to your DNS.
  5. After you've added the records to your DNS, return to Insightly. Click Validate.
  6. Click Close.
  7. If your records are still invalid, you can click Close and return later. The sending domain will not be included in outgoing emails until they are validated, however.

If you are having trouble with setup, we recommend visiting your provider’s help center to find more information.
