How can I choose and configure a sending domain?

A sending domain is used to set up your server, however, it’s not the same as your “from field”. It will be used to host your user panel and your sending infrastructure. It will appear in every message you send through GetResponse MAX in the message headers. This means that it might show up in different places, depending on the email clients, which your recipients might use.

Please keep in mind that in some cases it will also show alongside your from field as an additional field. Note: you add from fields later on when you have access to a fully configured account, and you can have as many from fields as you want.

The sending domain will be visible in:

  • the headers of all emails sent from your GetResponse MAX account,
  • right next to the “From” email on Gmail or Outlook, however this will happen only if you don’t authenticate the domain with DKIM
  • the opt-out and “change contact details” links,
  • all links in the body of your messages once the click-tracking functionality is enabled,
  • the URLs of your landing pages which haven’t been redirected to an external domain
  • the URLs of your webforms
  • webinars

It’s really important that you choose your sending domain wisely. It won’t be easy to change it after the initial setup and changing it might involve an additional cost.

GetResponse MAX enables you to have multiple sending domains, however please keep in mind that each sending domain requires at least one sending IP address assigned to it. This means that your contract needs to include the correct number of IP addresses that you need, based not only on the email volume you want to send on a regular basis, but also on how many sending domains you plan to use.

To give you an example, a contract including three IP addresses can give you different
configuration options, like:

  • One sending domain with three IP addresses assigned to it allows for higher sending speed, quicker warmup, and better deliverability (sending is routed through three IP addresses.)
  • Three sending domains one IP address assigned to each allows for more branding flexibility, as you can create different accounts in your GetResponse MAX server and each account can have its own dedicated domain (with the branding you want) and a dedicated IP address.

Choosing a sending domain

When choosing your sending domain, there are some general guidelines to follow:

  • don’t use a sending domain that’s already used for any other web page or a different mailing server, or for any other purpose than a sending domain,
  • don’t use a domain that has other records created. Please remove them if necessary,
  • you can use a subdomain (e.g. mailing.yourwebsite.com or newsletter.yourwebsite.com.),
  • you can use a new domain (mailingyourwebsite.com; newsletteryourwebsite.com etc.).

We recommend using a sending domain ending with .com or any other short popular format. Please avoid a domain ending with .biz .net .org .info and longer than three characters. Make sure the domain address is in lower case letters.

Please also take the following into account, when choosing your sending domain:

  1. It’s a good idea to use a domain name that refers to your company name or product (but it’s not a must.)
  2. Don’t use the name “getresponse” in any form in your domain name.
  3. The name should be no longer than 32 characters (some mailbox providers will refuse to create feedback loops if it’s longer).
  4. Don’t use a directory in the domain (e.g. yourwebsite.com/mailing.)
  5. The domain name should be publicly available with no privacy service used to conceal the contact data, meaning the domain’s registrant data can’t be hidden. You can see if your data is public or not by testing the sending domain here: http://www.whois.com (this prevents many major mailbox providers from whitelisting the mailing server).

Note: You will also need to configure your sending domain according to the information from support.
