Mailforge is Salesforge's distributed cold email infrastructure: mailboxes on a shared IP pool built specifically for outreach, with DMARC, SPF, DKIM and tracking domains configured automatically. It works with any sending software, and the vendor reports more than 10,000 businesses using it.
Product Overview
Mailforge is not Google or Microsoft — it is purpose-built mail infrastructure on a shared IP pool, similar in principle to how Gmail spreads users across shared IPs. The trade is cost: the vendor prices 200 mailboxes at roughly $484/month versus about $1,200–1,680 on MS365 or Google Workspace. It includes bulk DNS updates, pre-warmed domains and mailboxes, multiple workspaces, domain transfers and an SSL/domain-masking add-on. The vendor pitches it for teams starting out, or those expecting enough spam complaints that isolating them on shared infrastructure is safer.
RevOps Jobs-to-Be-Done
- Low-cost outbound capacity — Add sending capacity across many domains at a fraction of Google Workspace cost. KPI: Lower infrastructure cost per email sent.
- First outbound programme — A guided setup and calculator size domains and mailboxes to planned contact volume. KPI: Correctly sized infrastructure from day one.
- Diversify sending infrastructure — Run Mailforge alongside Google/Microsoft mailboxes so one provider's issue does not stop all sending. KPI: More resilient outbound programme.
Key Features
- Automated DNS setup: DMARC, SPF, DKIM and custom domain tracking per domain.
- Bulk DNS updates: Change records across many domains in a few clicks.
- Pre-warmed domains and mailboxes: Start sequences without waiting out warmup.
- Workspaces and domain transfers: Organise per project and move domains in or out.
- SSL and domain masking: Add-on that shows branded sites without exposing the primary domain.
How It Fits Your Stack
Primary system of record: None — sending layer; works with Salesforge or any sequencer
Key integrations: Salesforge, Warmforge
Data flows: Domains and mailboxes are created in Mailforge and connected to the sequencer; warmup and reputation monitoring typically run in Warmforge.

Implementation & Ownership
- Time to first value: Under 10 minutes per vendor

- Indicative range: $2–3 per mailbox per month ($3 on monthly-equivalent yearly billing); .com domains $14/year

Who It's Best For
Small and mid-size teams starting cold outreach, or cost-sensitive agencies adding volume, who accept shared-IP infrastructure.
Good fit if:
- Cost per mailbox matters more than provider brand
- You are building your first outbound programme
- You already use Salesforge or Warmforge
Probably not ideal if:
- You need a dedicated IP (see Infraforge)
- Your recipients filter aggressively on non-Google/Microsoft senders
Pros
- Roughly a third of the cost of Google Workspace per mailbox, per vendor comparison
- Fast guided setup with volume calculator
- Slots let you delete and recreate mailboxes at no extra cost
Cons
- Shared IP pool — reputation is not fully in your control
- Minimum 10 mailbox slots, billed whether used or not
- Not Google/Microsoft, so no ESP matching
Often Compared With
- Infraforge — Sibling product — Infraforge adds dedicated IPs and API for teams that need control at scale.
- Maildoso — Both are SMTP infrastructure; Maildoso is cheaper at volume with auto-rotating IPs, Mailforge fits the Forge stack.
- Salesforge — Complementary — Salesforge sends the sequences that run on Mailforge mailboxes.
