Nitrosend vs Mailsoftly.

Priced on sends, unlimited contacts, the agent surface on every plan, and BYO transport.

TL;DR

Mailsoftly is email marketing and automation software for small teams, sold on a calm screen, AI in the working surface, and a person on support. The plan limit is the size of your list: four tiers from a free 500 contacts up to 30,000 on Premium, each with a monthly send cap attached, and their team does the move for you free on any paid plan. If that's the shape of your program, it's a straightforward buy.

Nitrosend is an AI-native email platform. It specializes in email and prices on sends, with contacts unlimited on every plan including Free. Mailsoftly has shipped a real MCP server, so this isn't a page about an incumbent with no agent surface. It's a page about where that surface starts and stops: API access and webhooks open on the $159 Premium rung, and the automations that decide when mail goes out sit outside the API.

Where the agent surface starts is also the thing separating ManyReach, Maropost, and Moosend, so it is worth checking the same rung on each before you pick a ladder.

Pricing math

What you actually pay.

The two ladders are priced on different things: Mailsoftly on the contacts you hold, with a monthly send cap attached to each tier, and Nitrosend on the emails you send, with contacts unlimited. So each row names both.

Migration

How to switch (or run both).

Mailsoftly keeps sending while you move, there's no contract to exit, and plans upgrade, downgrade, or cancel from billing settings.

  1. Add and verify your sending domain in Nitrosend. DKIM and SPF records sit alongside Mailsoftly's, so both platforms send from the same domain for as long as the overlap lasts.
  2. Export your contacts with their tags and custom fields, and import them with nitro_import_contacts. Tags map onto lists and custom fields onto custom fields, so the shape survives the trip. On Premium that export is an API read; below it, a dashboard export.
  3. Move one low-stakes message type first: a receipt or a password reset sent with nitro_send_message, watched for a week before a campaign follows it.
  4. Rebuild your automations as flows with nitro_compose_flow. This step is a read-and-rebuild rather than an export, because Mailsoftly's automations endpoint isn't live yet, so nothing comes across programmatically and the triggers, steps, and branches get recreated by hand. Budget real time for it.
  5. Decide what carries your reputation. BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, and Mailsoftly's own pool isn't one of them, so what travels with you is the domain and its authentication history.
Honest credit

What Mailsoftly does well.

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

  • A free plan that stays free: 500 contacts and 2,000 sends a month, with no card and no trial clock.
  • Free hands-on migration on any paid plan, with their engineers moving contacts, templates, segments, and automations.
  • That migration runs in parallel with your current sender, so nothing stops sending while it happens.
  • Human support on every plan, with phone and priority support from Business and video calls on Premium.
  • Onboarding sessions in the price rather than as a service line: one on Business, four on Premium.
  • Contact-based pricing is predictable, because the bill follows the list size and is knowable before a campaign goes out.
  • Unsubscribed, bounced, and cleaned contacts don't count against the plan limit.
  • AI sits in the working surface: subject line suggestions, generated content, and a brand kit built from a pasted website URL.
  • A real MCP server, with published setup for Claude Desktop, ChatGPT, Gemini, Grok, and Copilot.
  • A dedicated sending IP as a $79 add-on on any plan, rather than only at the top of the ladder.
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.
  • Mailsoftly's plan limit is the size of your list, so the bill moves when the list moves rather than when the sending does.
  • A free tier a sender can work on: 8,000 emails to start, then 500 a month, with the full MCP, API, and CLI on it.
  • The agent surface isn't a plan feature here. API access and webhooks start on Mailsoftly's $159 Premium rung.
  • MCP-first is an architecture, not an integration: every capability at Nitrosend is an API endpoint and an MCP tool before it's a screen.
  • Mailsoftly's published endpoints reach authentication, contacts, lists, tags, and email drafts and sends.
  • Automations, forms, and landing pages are marked coming soon there, so the flows that decide when mail goes out stay in the dashboard.
  • BYO sending keys on Pro and above route your mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, on the domain and IP you already warmed.
  • A published price from 500,000 to over 4,000,000 emails a month, where Mailsoftly's ladder ends at 30,000 contacts and turns into a custom quote.
Use case fit

When to pick which.

Pick Mailsoftly if

You want the move done for you rather than done yourself, by a team that lifts contacts, templates, segments, and automations across while your current sender keeps running. A person on the phone and four onboarding sessions in the price both point the same way, and so does a list that's small relative to what you send it, where a contact tier is simply the cheaper shape. Forms, landing pages, and a brand kit in the same product as the campaigns close it. None of those are close calls.

Pick Nitrosend if

Your list is much larger than your send volume and you're tired of paying for addresses you don't mail. Campaigns and transactional email run on one set of contacts here rather than two. It's also the right call when you want the agent surface and the email API on the plan you're already on rather than at the top of the ladder, with the flows inside them rather than sitting outside. The same goes for keeping your own transport underneath a platform that can change.

FAQ

Mailsoftly vs Nitrosend - common questions.

Can Nitrosend replace Mailsoftly?

For the email program, yes. Campaigns, flows, segments, templates, contacts, and transactional sending are all here, and the agent surface over them is on every plan rather than on one rung. What doesn't come across is the service around the software: Mailsoftly's team does your migration for you on any paid plan and puts four onboarding sessions in the Premium price, and we don't replace either of those.

Is Nitrosend cheaper than Mailsoftly?

It depends which end of the ladder you're on. At 5,000 contacts, Pro is $20 against Basic at $39. At 15,000 contacts Mailsoftly is cheaper on headline price, $79 Business against $100 Ultra. Above 30,000 contacts their published ladder stops and turns into a custom quote, where ours is $300 for 500,000 to over 4 million emails a month. The two are priced on different things, contacts held against emails sent, so the answer moves with your ratio.

Mailsoftly has an MCP server too. What's actually different?

Order of construction, and what it reaches. Mailsoftly built a dashboard, then an API under it, then exposed that API to agents. Nitrosend was built the other way round, so every capability is an endpoint and a tool before it's a screen. The practical test is the edges: their published endpoints cover authentication, contacts, lists, tags, and email drafts and sends, the automations and forms are marked coming soon, and API access starts on the $159 Premium plan.

Can I keep sending through Mailsoftly while I move?

On the domain, yes. Both platforms can authenticate against the same sending domain, so you can move one message type at a time and leave the rest where they are. What you can't do is point Nitrosend at Mailsoftly's transport: BYO sending keys cover Amazon SES, Resend, Postmark, Mailgun, and SendGrid, and Mailsoftly's own pool isn't one of them. What travels with you is the domain and its authentication history.
