How we grade them
| 1.6GPAInfraforgeWeak | 2.8GPASalesforgeGood | |
|---|---|---|
| Value for money | C$4 a slot a month on quarterly billing, with a 10-slot minimum, so $40 at the floor. That sits mid-category before domains and add-ons. | APro is one user, so five people need Growth, which has unlimited users: $80 a month billed annually, $16 a head. That's under 60% of the cheaper quarter's $32.50, though AI writing and LinkedIn actions draw on monthly credits. |
| Free plan and trial | FNo free plan and no trial. Each Forge product is a separate subscription. | CNo free plan. The 14-day trial gives 50 contacts, 100 emails and one LinkedIn profile, enough to see the AI writing but not a real campaign. |
| Features | DDomains, mailboxes, DKIM, SPF and DMARC, warm-up and rotation. But it only supplies the sending infrastructure and needs another product to send. | BThe whole job: email and LinkedIn sequences with profile views, requests and messages, unlimited mailboxes with warm-up and rotation, AI-written first emails and Primebox for replies. Multi-language sequences, A/B tests and AI reply drafts need Growth. |
| Ease of use | CNo store rating on record. Automatic DNS setup, but you buy domains, build slots and connect a sender. | CNo App Store rating on record. Mailboxes and domains to connect, often bought from separate Forge products, and credits to keep an eye on before sending. |
| Platforms and integrations | BWeb with an API, and a Forge family of Salesforge, Mailforge, Warmforge and Primeforge. | BWeb only, with HubSpot, Salesforce, GoHighLevel, Clay, Make, folk and Claude, plus an API, an MCP server and a command-line tool on Growth. No phone or desktop app on record. |
| Best for | dedicated-server mailboxes for cold email | AI-written first emails from many mailboxes |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
