Deliverability of your messages is one of Herefish's most important responsibilities. We will help you to stay compliant, suggest best practices and have features built into the system to help maintain a great sending reputation. 

In addition to those steps, there are some technical steps you will want to take to help get as many messages into the inbox as possible. No matter which approach you send, all messages will appear to be sent from your domain and when a contact responds, those responses will come back to whoever they were sent from.


The ideal approach is for Herefish to white-label a new sub-domain. This takes some involvement from your IT team, but it is a straight forward process. This ensures the highest deliverability. 

By whitelabling your domain, you will start to build your domain’s email reputation and explicitly show all your recipients that you actually sent these emails. This should help increase your deliverability rates and reduce your potential for spam reports.

The steps for the process are as follows

  • Herefish will send you an email with all of the information you'll add to your domain. 
  • You will then forward that information to your IT team or add them on your own
  • You or your IT team will then add 4 new CNAMEs to your DNS Records. If you need help, you can run the following search in google, then add the name of your hosting provider. 
  • Once this is complete, please confirm with your account rep or send an email to and Herefish will complete the process.

High volume 

Customers who send over 100,000 emails per month will follow the steps above, but will be provided with their own IP address from Herefish.

Alternative approach (not recommended)

If for some reason we are not able to take the steps outlined above, we can also add our mail IP address to your SPF record. We will send you the IP address that you'll be using. The process for adding our IP to your domain will vary based on your provider. A simple google search or just telling your IT person is likely the best approach.  For google, start with this search and then add the name of your provider at the end.

Taking this approach will generally get great delivery, but could land in the "Promotions" tab. This isn't always a bad thing, but isn't ideal when sending personalized messages. 

When sending this way, it will look like this in a gmail inbox:

Note - You'll see we use "" as the domain for our customers, this is done to ensure your recipients have no idea that Herefish is involved.
