The Google Workspace playbook

Gmail sends your mail. Your domain still has to earn the inbox.

Every message from a Workspace mailbox leaves through Google’s shared servers, so the sending IP is never yours. The domain is, and Google offers no warmup for it, only advice to raise volume slowly. Keep sending from Gmail exactly as you do. Add the domain here and we build its reputation.

The Google Workspace playbook

Keep sending from Google Workspace. Warm the domain here.

Step 1

Authenticate the domain in the Admin console

Publish one SPF record with include:_spf.google.com, generate a DKIM key under Apps > Google Workspace > Gmail > Authenticate email and publish it as a TXT record, then add DMARC, starting at p=none. From 2024, Gmail and Yahoo require bulk senders to authenticate with SPF, DKIM and DMARC.

Step 2

Know what Google does, and what it does not

Workspace has no warm-up feature. Google’s sender guidelines say to start with a low volume to engaged recipients, increase it slowly, avoid sudden spikes and slow down when messages are deferred or bounce. Per-user sending limits cap each mailbox, and Postmaster Tools scores the reputation of your domain.

Step 3

Add your sending domain to Inbox Boost

Add the domain your mailboxes send as, the one in your From address, such as yourcompany.com, and we set up what it needs and build its sender reputation for you. Nothing to connect to Google Workspace: no Admin console access, no app, no change to your mailboxes.

Step 4

Keep everyday mail and outreach going from Gmail

Replies, proposals, sales email and the tools that send through your mailboxes: all of it stays as it is. Mailbox providers score the domain in your From address, so the reputation built here counts for every mailbox sending as yourcompany.com.

Step 5

Check where your mail lands

Inbox placement tests show whether your mail reaches Primary, Promotions or Spam across the major mailbox providers, and blacklist monitoring keeps watching the domain once it is warm.

  • Nothing to connect: no Admin console access, app or add-on
  • Nothing to change: mailboxes, users and mail routing stay exactly as they are
  • Every mailbox on the domain: the reputation belongs to the domain, so they all share it
  • Watched after warmup: blacklist and authentication monitoring on your sending domain

Questions

Google Workspace questions, answered.

Does Inbox Boost need access to our Google Workspace?
No. There is no Admin console access, app or integration to install. Inbox Boost works on the sending domain, and your mailboxes keep sending from Gmail exactly as they do now.
Google sends from its own servers. Why does my domain matter?
Workspace mail leaves through Google’s shared servers, so the sending IP is never yours. Google’s Postmaster Tools reports a separate reputation for the domain used in SPF and DKIM, and that is the reputation you can build or damage. It is what we build.
Does Google warm up a new domain?
No. Workspace has no warm-up feature. Google’s sender guidelines say to start with a low volume to engaged recipients and increase it slowly, and they treat a domain without a history of bulk sending to Gmail as new.
Is it safe to run sales outreach from Workspace mailboxes?
Within Google’s rules. Its Acceptable Use Policy forbids unsolicited mass email, and if a problem is domain-wide Google reserves the right to suspend the entire account. Keep outreach permission-based and paced, because every mailbox on the domain shares its reputation.
Can I see whether it is working?
Yes. Inbox placement tests show where your mail lands, Primary, Promotions or Spam, across the major mailbox providers, and blacklist monitoring keeps watching the domain afterwards.
