When to choose Infraforge vs Maildoso (and when to walk away)
Choose Infraforge if
- Target ICP & Stack Fit: You operate as Cold Email teams requiring a Web SaaS deployment for Cold Email, with verified ecosystem connectivity for Outreach, Google Workspace, Google Ads.
- L2 Architecture & Defensibility: Infraforge commands a strong deliverability infrastructure moat inside the Forge ecosystem through dedicated IP clusters, automated DNS/DKIM/DMARC provisioning, multi-IP rotation, and native Salesforge/Warmforge integration.
- Commercial Model Fit: Your procurement budget aligns with $14–$112/mo.
Walk away from Infraforge if
- Walk away if your workflow requires uncapped enterprise volume on the $14–$112/mo entry plan without upgrading tiers.
- Walk away if your workflow cannot tolerate automated domain & DNS provisioning: Purchases secondary `.com` and alternative TLD domains inside the dashboard and automatically configures SPF, DKIM, DMARC, and forwarding records in minutes.
- Walk away if private dedicated IP & multi-ip rotation is a deal-breaker for your team: Assigns isolated IP infrastructure (`$99/month` for dedicated IP upgrades) so an agency's deliverability is never degraded by noisy neighbors on shared hosting servers.
Choose Maildoso if
- Target ICP & Stack Fit: You operate as Cold Email teams requiring a Web SaaS deployment for Cold Email, with verified ecosystem connectivity for Model Context Protocol (MCP).
- L3 Architecture & Defensibility: Maildoso commands a strong outbound email infrastructure moat through its self-healing mailbox clusters, automated IP rotation, CAPTCHA domain protection, reputation telemetry, and native API/MCP access.

- Walk away if automated domain setup & captcha protection is a deal-breaker for your team: Handles domain registration, bulk DNS configuration (SPF, DKIM, DMARC), and CAPTCHA-protected domain redirects so prospect clicks and security scanners never flag bare domains.

Infraforge
Low Procurement Risk · Strong Fit- Published Self-Serve Entry Floor: Infraforge publishes a transparent entry point ($14–$112/mo) for initial validation before committing.
