What Mailforge (Salesforge) is

Mailforge is the shared-infrastructure email product in Salesforge's suite of cold outreach tools, letting outbound teams spin up domains and mailboxes across a shared IP pool for cold email sending. It automates DNS configuration (SPF, DKIM, DMARC), mailbox provisioning and domain masking so agencies and sales teams can get sending infrastructure live in minutes rather than days.

Mailforge is built to plug directly into Salesforge's outreach sequences, and mailboxes purchased through it can also be used with other cold email tools. Pricing is based on domains and mailbox slots, with the platform recommending multiple mailboxes per domain and limited daily sending volume per mailbox to protect deliverability.

It sits in the email marketing & esps part of an email stack - campaign, lifecycle and transactional sending platforms. In practice it is the right pick when your priority is: teams running marketing, lifecycle or transactional email.

What it does well

The capabilities teams rely on most are campaign and automation builder, segmentation and audience management, delivery and engagement reporting. Taken together these cover the day-to-day work in this category, and they are the features worth testing during a trial rather than reading about.

The fully automated domain and mailbox setup, including DNS and SSL/domain masking, removes most of the manual work of building cold email sending infrastructure at scale, which is valuable for agencies running many client campaigns simultaneously.

In real use the strongest points people report are one place for audience, content and sending; established deliverability infrastructure.

Pricing tiers

Mailforge (Salesforge) is a free trial product. Domains priced per year (around $14/year for .com), plus mailbox slots sold in minimum blocks (roughly $3/month per slot, discounted on annual billing), calculated based on desired sequence volume and mailboxes per domain.

Pricing pages move often, so confirm the current figures with the vendor before you budget. The number worth modelling is not the licence fee on its own but the cost per delivered email once bounces, suppressed contacts and spam-foldered sends are taken out.

Ideal customer profile

• Best fit: Teams running marketing, lifecycle or transactional email.
• Where it sits in the stack: Email marketing & ESPs - campaign, lifecycle and transactional sending platforms.
• Budget profile: Free trial - suited to teams comfortable with this commercial model.
• Probably not for you if: shared sending infrastructure means neighbours affect reputation would block your team.

What it connects to

Mailforge (Salesforge) is commonly wired into Salesforge sequences, Google Workspace, Microsoft 365, SMTP/IMAP senders, Warmforge (warm-up), Infraforge, Primeforge, Zapier, CRM exports (CSV) and API access. Check that the specific objects and events you rely on are covered, not just that a logo appears on the integrations page - shallow connectors are a frequent source of rework.

Where it falls short

No tool in this space is complete on its own. With Mailforge (Salesforge) the trade-offs to plan around are shared sending infrastructure means neighbours affect reputation; platform reporting rarely shows true inbox placement. None of these are reasons to avoid it - they are the gaps another layer of your stack needs to fill.

Shared IP pools mean sender reputation can be influenced by other Mailforge customers on the same infrastructure, and the tool is purpose-built for cold outreach rather than permission-based marketing email, so it should not be used for opted-in newsletter sending.

A useful test before committing: send a real campaign through your intended setup, then check where it actually lands across Gmail, Outlook, Yahoo and your customers' corporate filters. Tooling that looks identical on a feature list often behaves very differently once reputation and authentication are involved.

Yes - warm-up, placement, DMARC

How it fits a deliverability stack

Deliverability is decided by four things: the reputation of the sending domain and mailbox, the quality of the list, correct SPF, DKIM and DMARC authentication, and proof of where mail actually lands. Mailforge (Salesforge) covers part of that picture. The mistake most teams make is buying four separate products for those four jobs and still having no single place that tells them whether the last campaign reached the inbox.

Warmy runs warm-up, inbox placement testing, email verification and DMARC monitoring as one platform, which is why Mailforge (Salesforge) usually sits alongside it rather than against it: it keeps doing what it is good at, while reputation, placement and authentication are handled in one loop.

Mailforge recommends capping sends per mailbox (around 30-100 emails/day) and pairing new domains with warm-up before scaling volume, since shared-IP cold email infrastructure is more sensitive to spam complaints than dedicated marketing ESP sending.
