How to Set Up Google Postmaster Tools?
This guide explains how to add your sending subdomain (for example hello.domain.com) to Google Postmaster Tools, and how to grant read access to Batch's team.
Why This Matters
Google Postmaster Tools provides essential, Gmail-specific metrics for your top sending destination:
Spam complaint rate
SPF/DKIM/DMARC authentication
TLS encryption
And more
No other tool gives you this visibility: these metrics are unique to Postmaster Tools, and they're indispensable for monitoring your deliverability and reacting fast if something degrades.
Prerequisites
A Google or Google Workspace account (corporate or team-shared) to sign in to Postmaster Tools.
Access to the DNS zone for the domain in question (usually asking your backend team).
The exact subdomains used for sending through Batch, e.g. hello.domain.com.
The address to add with read access: deliverability@batch.com.
Add and Verify your Subdomains
Verify the Subdomain
Return to the Manage domains view. You will see your newly added subdomain. Click the three-dot menu next to it, then select Verify.

You need to add a DNS record to verify you own the subdomain. Google Postmaster Tools supports two options. Use the "CNAME" verification option.

Log in to the DNS management console for your domain with your host or DNS provider (OVH, Cloudflare, GoDaddy, etc.). Create the required record and save your changes. Then return to Postmaster Tools and click Verify.
Verification is usually immediate, but can take a few hours depending on DNS propagation.
Share the Report with Batch
Sharing Postmaster Tools data with Batch's customer and deliverability team helps them support you better. Postmaster Tools reports do not contain personal data, such as recipient email addresses.

Once your subdomain is verified, you can invite others to view its dashboard. To do so:
On the Manage Domains page in Postmaster Tools, find your subdomain.
Click the three-dot menu (⋮) to the right of the domain name, then select Manage users.
Click the + button in the bottom-right corner of the window.
Enter the following address deliverability@batch.com, then confirm.
Click Done. Access takes effect immediately.
