Nitrosend vs Salesforge.

Cold outbound is one job. Lifecycle email on a domain you own is another.

TL;DR

Salesforge is a cold outreach platform. It sends through mailboxes it provisions for you or ones you connect, warms them without a slot limit, runs email and LinkedIn steps in the same sequence, and pulls every reply into one inbox. It does that job well, and it's driveable by a first-party MCP server and CLI rather than only a dashboard, which puts it at the outbound end of our comparison index.

Nitrosend is a different product. Campaigns, flows, segments, and transactional mail leave your own authenticated domain, contacts are unlimited on every plan including Free, and BYO sending keys on Pro and above keep the transport yours. Every capability is an email API endpoint and an MCP tool before it's a screen, and the whole lifecycle answers to one credential rather than a surface stretched over six separately authenticated products. This is email to people who gave you their address. If the job is prospecting strangers, Salesforge is the answer and we won't pretend otherwise.

Pricing math

What you actually pay.

The two ladders meter different things, and Salesforge's plan price is a floor rather than a total: the sequencer is one subscription, and the mailboxes, domains, lead search, and placement testing are separate Forge products bought on top, each mailbox product with a ten-slot minimum.

Scenario	Nitrosend	Salesforge
Getting started	Free: 8,000 emails to start, then 500/mo forever. Unlimited contacts, full MCP, API, and CLI	No permanent free tier. A 14-day trial on both plans, and the ladder opens at $40
5,000 emails/mo, 1,000 contacts	$20 Pro: 20,000 emails, unlimited contacts, 3 seats, BYO sending and AI keys	$40 Pro: 5,000 emails, 1,000 active contacts, 1 user, 1 LinkedIn sender, unlimited mailboxes and warm-up
50,000 emails/mo, 10,000 contacts	$100 Ultra: 125,000 emails, unlimited contacts, 5 brands, 10 seats	$80 Growth ($64 annual): 50,000 emails, 10,000 active contacts, unlimited users and LinkedIn senders. Top of the published ladder
Above that, and the mailboxes	$300 Enterprise: 500K to 4M+ emails at a published price, with the sending included	Nothing published above Growth. Mailboxes are bought separately, from $3 per mailbox per month on annual billing with a ten-slot minimum, plus $14 a year per domain

Migration

How to switch (or run both).

This one is a split rather than a port. Salesforge sends through mailboxes it provisions or that you connect, so there's no sending key to carry across. The upside: you aren't moving the prospecting motion at all.

Verify a sending domain in Nitrosend with DKIM and SPF, and make it a different domain or subdomain from the ones running cold outbound. Prospecting domains are bought to be spent. This one can't be.
Export the contacts who replied or converted, using Salesforge's documented API rather than doing it by hand, then import them with nitro_import_contacts, consent status intact.
Move one message type first. Build onboarding or a product announcement as a flow with nitro_compose_flow, and watch it for a week before anything follows it.
Leave the cold outreach alone. The mailbox slots, the warm-up, and Primebox stay on Salesforge, and the Forge mailbox subscriptions are billed separately from the sequencer anyway, so nothing in this move forces a cancellation.
Point the owned-audience sending at a transport you control. BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, so the domain and the IP are yours, warming on your own reputation rather than inheriting one.

Honest credit

What Salesforge does well.

Picking a tool is about fit. Here's what Salesforge is genuinely good at.

Unlimited mailboxes and unlimited warm-up on both plans, including the $40 entry rung.
Email and LinkedIn steps run in the same sequence, with LinkedIn senders unlimited on Growth.
Primebox pulls replies from both channels into one place, so nobody is switching tabs to answer a prospect.
A first-party MCP server reaching six Forge products from one endpoint, which is a genuinely agent-native surface.
A first-party CLI that runs the same stack from a terminal, so scheduled and scripted work doesn't have to go through an agent or a dashboard.
It sells the sending infrastructure itself: domains, automated DNS setup, and mailbox hosting.
Mailbox billing is per slot rather than per active mailbox, so mailboxes can be recycled without extra cost.
Dedicated IPs and private infrastructure are a product you can buy, not a top-tier plan perk.
Deliverability has its own product: automated warm-up, placement tests, and DNS and MX health checks.
Agent Frank packages the whole prospecting motion with a dedicated account manager, for teams that would rather buy it than build it.

What Nitrosend adds

Where we think we're better.

Unlimited contacts on every plan, including Free, so a list that grows without being mailed never moves the bill.
Campaigns, flows, segments, and transactional mail in one platform, with the streams kept deliverability-isolated from each other.
Sending leaves your own authenticated domain through a transport built for volume, rather than out of mailbox slots bought ten at a time.
The sending is in the plan: no per-mailbox fee, no per-domain fee, and no minimum block to clear before the first send.
MCP-first is the architecture, not an integration: every capability is an API endpoint and an MCP tool before it's a screen.
The MCP reaches flows, segments, templates, and approvals, not only the sequence and the send.
Deliverability, billing, and tests are tools too, and they're the three that usually stop an automation dead halfway through.
One credential covers the platform, rather than a separate key for each product in the stack.
Transactional sends stay on the REST API, because a send that has to be fast shouldn't wait on a tool call.
BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, on a domain and IP you already control.

Use case fit

When to pick which.

Pick Salesforge if

You're sending cold, to people who've never heard of you. You need mailboxes provisioned, warmed, and rotated, and you'd rather buy that than build it. You want LinkedIn and email steps in one sequence, and the lead search and the reply inbox sitting in the same tool that does the sending. None of those are close calls. Salesforge owns the mailbox layer: it provisions and rotates them, and it reads what comes back. There's no version of Nitrosend that does this job.

Pick Nitrosend if

Your email goes to people who gave you their address, and lifecycle and transactional mail are running together on a domain you own. You want the platform driveable by an agent rather than a dashboard, across more than the sending, and you'd rather a contact count didn't decide your bill. The clearest case is a team already running Salesforge for prospecting with nowhere for onboarding sequences, product announcements, and receipts to live. That's a split, not a switch, and it's the one we'd argue for. Teams pricing the outbound tools against each other usually shortlist Saleshandy at the same time, and read Selzy and Sender when the lifecycle half is contact-priced elsewhere.

Salesforge vs Nitrosend - common questions.

Can Nitrosend replace Salesforge for cold outreach?

No. Salesforge owns a layer Nitrosend doesn't have: mailboxes it provisions, warms, and rotates, and a sequencer that pulls replies into one inbox. Nitrosend specializes in email to people who gave you their address, sent from your own authenticated domain. For prospecting, keep Salesforge.

Salesforge has an MCP server and a CLI. What's actually different?

Scope, and how far the surface reaches. Theirs drives the outbound stack across six Forge products, each authenticating with its own key. Ours covers campaigns, flows, contacts, segments, templates, deliverability, billing, tests, and approvals under one credential, with transactional sends left on REST and the SDK because a send that has to be fast shouldn't wait on a tool call.

What does Salesforge actually cost once the Forge stack is added?

The sequencer is $40 or $80 a month. Mailboxes are bought by the slot from $3 each on a ten-slot minimum, domains are $14 a year, and lead search and the AI SDR are separate subscriptions again. The plan price is the floor rather than the total, so price the pieces you'll actually switch on before you compare ladders.

Can I run Salesforge and Nitrosend together?

Yes, and it's usually what we'd recommend. Prospecting stays on Salesforge, on domains bought to be spent and rotated. Owned-audience email moves to a domain you can't afford to burn, with its own DKIM and SPF records and its own reputation. Keeping those two domains apart is the operational point this whole comparison rests on.
