Where your email infrastructure is physically located matters more than you think

PSA for anyone targeting US or EU prospects with cold email.
I audited a client's setup and found their Google Workspace inboxes were provisioned through an Indian reseller. Deliverability to US prospects was terrible — poor reply rates. We moved everything to US-provisioned Google Workspace through PuzzleInbox. Same domains, same copy, same sending platform. Reply rates improved significantly.
The physical location and provisioning path of your email infrastructure matters because Google and receiving servers factor in the geographic origin and reputation of the Google Workspace reseller. Some resellers have terrible reputations due to abuse by other customers.
Always ask your inbox provider where and how they provision accounts. Reputable providers like PuzzleInbox use direct Google Workspace provisioning which gives you the cleanest possible sending reputation from day one.

Dedicated warmup tools (Warmy, MailReach, etc.) generally outperform built-in warmup from sending platforms. The warmup networks are larger and more diverse. That said, pre-warmed inboxes that skip warmup entirely are gaining popularity. Saves the 14 day minimum wait and the monthly warmup cost.

used Instantly's built-in warmup for 6 months. it's... fine. not great. when i switched to dedicated warmup my deliverability and reply rates improved noticeably. the bigger warmup networks just build better sender reputation faster imo

honestly if you're paying for a separate warmup tool on top of your sending platform on top of your inboxes, you should just get pre-warmed inboxes from whatever provider you trust. the math of paying for warmup separately just doesn't make sense anymore
