Mailforge vs Mailscale: SMTP vs Shared Google Workspace Compared

Mailforge is self-service SMTP. Mailscale is shared Google Workspace. Here is which cold email infrastructure model actually delivers better results.

Mailforge vs Mailscale: Two Different Infrastructure Models

Mailforge and Mailscale represent different philosophies in cold email infrastructure. Mailforge gives you raw SMTP infrastructure — your own servers, your own IPs, full control. Mailscale provides Google Workspace inboxes on shared sending infrastructure. Both target budget-conscious cold email teams but with very different trade-offs.

Feature	Puzzle Inbox	Mailscale
Infrastructure type	SMTP	Google Workspace shared
IP reputation start	Zero (self-warm)	Inherited from pool
Setup complexity	Technical	Simple
Deliverability out of box	Poor (warming)	Variable
Starting price	$29-79/month	$2-4/inbox
Time to send	2-4 weeks	24-72 hours
Support model	Self-service	Email

Infrastructure Philosophy

Mailforge: You get raw SMTP servers and IPs. Build your reputation from scratch. Full control, but zero starting reputation means weeks of unpredictable deliverability.

Mailscale: Google Workspace inboxes inherit Google's infrastructure reputation. Shared sending pool means your deliverability is partially determined by other users.

Deliverability

Mailforge after 4 weeks of warm-up: 2-3% reply rate at low volume. Higher volume builds reputation faster.

Mailscale from day one: 1.5-3% reply rate, variable by shared pool.

Setup Time

Mailforge: 1-2 weeks of technical setup plus 2-4 weeks of IP warming. Total: 3-6 weeks before effective sending.

Mailscale: 24-72 hours to first send. But deliverability is volatile due to shared infrastructure.

Cost at 30 Inboxes

Mailforge: $199-299/month for shared SMTP tier. Technical expertise required.

Mailscale: 30 × $3 = $90/month plus warmup tool ~$450/month = $540/month all-in.

When Mailforge Wins

Technical teams sending 50K+ emails/day with dedicated deliverability engineering
Long-term operations willing to invest in infrastructure
Compliance/security requirements for private infrastructure

When Mailscale Wins

Teams wanting quick Google Workspace setup
Non-technical operators
Short-term or testing use cases

Verdict: Both providers target budget cold email but both have structural limitations. Mailforge is slow to deliver results. Mailscale produces variable deliverability. For most cold email operations, pre-warmed dedicated Google Workspace inboxes from Puzzle Inbox outperform both at comparable all-in cost with fast setup and dedicated infrastructure.
