Using a custom subdomain allows Siftrock to directly capture and process the replies to your marketing email. There are 3 steps you will need to complete, each outlined in more detail below:
- Create a DNS record for your subdomain, pointing an MX record to Siftrock.
- Set-up DKIM signing and a SPF record for your subdomain.
- Update the FROM and REPLY TO fields in your MAP to use your subdomain.
Marketo Users, you can skip this guide and use our subdomain set-up worksheet - this makes it easy to give IT exactly what they need to complete your DNS configuration.
1.) DNS Settings: Point your reply subdomain to Siftrock
Edit the DNS for your subdomain so it points to our server. Note: Our server will only handle replies -- this does not impact your sending at all.
You need an A Record like this:
hello.yourcompany.com A 126.96.36.199
You need an MX Records like this:
hello.yourcompany.com MX 10 smtp.siftrock.com hello.yourcompany.com MX 20 smtp2.siftrock.com
This will direct emails to any address @hello.yourcompany.com to the Siftrock mail server.
2.) Configure DKIM signing and a SPF record for your subdomain
Note: This is not a required step for Siftrock to function, but it is a recommended best practice for deliverability.
Generally you will create a SPF record on your new subdomain that matches the SPF record on the domains you currently use for email marketing. In addition, you will want to configure DKIM signing in your MAP platform for your new subdomain. This requires adding the domain in your MAP admin for email domain management and passing the required DNS information to IT.

3.) Edit the FROM and REPLY TO fields to use the sub-domain on your next send.
You will need both the FROM and REPLY-TO fields in your campaigns using an alias at your Siftrock subdomain.
Our system wildcards the alias, so you can set the FROM and REPLY TO with any alias... i.e. webinars@, jennifer@, marketing@, etc.
Background: How it Works
Siftrock manages an inbound SMTP server that handles email responses on behalf of our customers. When someone in your organization sends an email they wish to have managed through our service the reply-to and from email address at a specific sub-domain is used to direct responses to the Siftrock SMTP server.
Best-practice for email marketers is to use a friendly sub-domain such as hello.domain.com or reply.domain.com. To make this work seamlessly we require an MX record to be configured in your DNS pointing at our mail server, and we highly recommend you also configure an A record as well.
Our mail server for handling customer replies is smtp.siftrock.com
Depending on your DNS provider it can take anywhere from a few minutes to a full day for the new sub-domain record to be available for use.
Once your DNS and software setup are complete your marketing team will be able to start using the new reply-to domain in all their outbound campaigns.
