Emails from centralnest.co.uk silently blocked. Either not reaching inbox or spam

Hi everyone,

I'm hoping someone from BT or the community can help with a persistent email delivery issue affecting one of my clients who is a BT Internet subscriber.

The problem: Emails sent from my domain centralnest.co.uk — specifically Google Workspace eSignature requests and Google Calendar meeting invitations — are either being silently blocked or landing in spam, despite my domain being fully and correctly authenticated. Regular emails from the same domain arrive without any issue.

What I've already checked:

✅ Domain checked against 70 email blacklists via MXToolbox — 0 listings, completely clean
✅ SPF record correctly configured (includes Google, Amazon SES, HubSpot)
✅ DKIM active and valid
✅ DMARC record published and syntactically correct
✅ The sending infrastructure is Google Workspace (drive-notifications.bounces.google.com)

The eSignature emails originate from esignature-noreply@google.com signed by google.com — a trusted, major sender. Neither my client nor I received any bounce or failure notification, suggesting the emails are being silently dropped at BT's gateway level before reaching the mailbox.

What I'm requesting: Could BT please whitelist the following so that my client receives all correspondence without issue:

Domain: centralnest.co.uk
Sending infrastructure: google.com / drive-notifications.bounces.google.com

My client's BT email address is at btinternet.com and this is affecting a live business contract (NDA signing).

Is there an official process to request domain whitelisting, or does my client need to contact BT support directly to resolve this?

Any help appreciated. Thank you.

This is a customer to customer self help forum, you need to contact the BT postmaster at postmaster@btinternet.com

Unfortunately, the response is glacial at best.
