I spent 7 years at Salesforce building compliance and trust infrastructure for one of the largest email senders in the world. During that stretch, I was the escalation point for ISP abuse desks and Spamhaus, which means I have spent years working the exact conversations your ESP is now trying to have on your behalf.
I speak at M3AAWG and Unspam, I sit on the board of Women of Email, and I have written the remediation cases that get senders unlisted. Threadsmith Group is where I bring that work directly to companies whose email programs have gone sideways.
When your program is broken and the clock is running, I'm the person you want reading the headers, writing the remediation case, and translating between your team and your ESP's compliance desk.
