DoYouMail vs InboxKit

Google, Microsoft 365 & Azure mailboxes with built-in warmup

WINNER

DoYouMail

Horizontal cold email infrastructure - scale with dedicated servers, not crammed domains

3-4 email IDs per domain per server - cold email best practice, not cramming
Horizontal scaling: add more dedicated servers to grow, not more IDs on one domain
100% private dedicated enterprise-grade IP per server - no shared reputation
Automated SPF, DKIM, DMARC, MX per domain - every server ready in minutes
Unlimited domains per server - spread IDs safely across domains
Unlimited sending volume at cold-email-safe per-ID rates (~50/day/ID)
Not a Google/Microsoft reseller - no TOS shutdown risk
Dedicated USA/EU infrastructure - you own the server

Cold email scaling model

Horizontal - add more dedicated servers to scale, each with its own IP and safe per-domain limits

Max Unlimited (Nudge at 3-4 - cold email best practice) per domain - cold email best practice

Google, Microsoft 365 & Azure mailboxes with built-in warmup

$2.50 /mailbox $31/mo Professional (10 slots), $81/mo Agency (30), $250/mo Enterprise (100). Azure mailboxes available.

Google/Microsoft reseller - cold email sending violates platform Terms of Service
Mailbox limits on every plan (10-100) - hard-capped by subscription tier
All mailboxes share the same tenant suspension risk - one violation wipes everything
$31/mo minimum for 10 slots - but you're paying for accounts that can be shut down
Azure tenants available but same reseller TOS risk applies
4.9 G2 rating but reseller risk is inherent to the model, not the service quality

Reseller risk

This provider resells Google/Microsoft accounts. Cold email violates their TOS - accounts can be suspended without warning.

Scaling model

Vertical - more IDs in the same tenant, same TOS risk

IDs per domain: Limited by Google/Microsoft/Azure tenant
