A subdomain is a prefix to the root domain, as in blog.yourcompany.com where “blog” is the subdomain for yourcompany.com (as seen in the photo above). If you’ve never heard of a subdomain mail server before, this article covers the basics.

In order to maximize email-deliverability, you may need to make efforts— such as setting up a subdomain —to ensure the security of your email-sending infrastructure.

We encourage users to implement email subdomains because doing so greatly increases the chance of your outreach getting to your prospective candidates' inboxes. It also protects your company’s primary email domain, thereby ensuring your other activities won’t become disrupted, because subdomains are treated as distinct from other related subdomains.

Follow the instructions below to increase the likelihood of experiencing higher open rates so you can hire qualified candidates, faster.

To strengthen the security of your email infrastructure, configure SPF, DKIM, and DMARC by following our instructions for getting the most emails to candidate inboxes.

Gmail Setup

  1. Click “Add a new domain”.

  2. Create a new subdomain. Keep it relatively simple— for example, if your company’s domain is “company.com”, choose a related term to use for your subdomain (e.g. “mail”, “team”). So, if your subdomain prefix is “team”, your outreach emails will come from yourname@team.company.com.

NOTE: Once setup, all correspondence will be directed to your standard, root domain address so that no extra work is needed.

  1. Strengthen your email security and experience higher open rates by configuring SPF, DKIM, and DMARC— follow our instructions for getting the most emails to candidate inboxes.

  2. Within the Gmail admin portal, create a brand new email address on your domain to send outreach. Referencing the above, perhaps your new email can be jane@mail.company.com, or doe@team.company.com.

If you do this, make sure you ramp up usage slowly, since these new accounts don’t have the credibility of older, more established accounts (see Step 8).

  1. Ensure you are logged in to the RecruitBot app.

  2. Link the new user email address to RecruitBot by following our instructions for How to Invite Others to RecruitBot (in this case, the “others” is the new user).

  1. OPTIONAL (but strongly recommended): Do some “email warming” to increase your email open and deliverability rates. Send emails to 10 people using the new account. Ramp your email volume slowly. 10/day, for a couple days, then 20/day for a couple days, and so on.

You can also use an email warming service like https://www.mailwarm.com/.

Other/Non-Gmail Setup

  1. Go to your domain registrar.

  2. Choose a needed domain.

  3. Open DNS settings.

  4. Add one record with following values: CNAME-record, "yoursubdomain" host.

  5. Save.

  6. Go to your email provider admin account. Click on "Add new domain".

  7. Add a new subdomain+domain name. ...

  8. Click on "Add a domain."

  9. Domain activation may take a few hours.
