Nitrosend vs Maropost.

Priced on sends, agent-native, unlimited contacts, and no annual commitment.

TL;DR

Maropost is a commerce suite, and Marketing Cloud is the email half of it. The storefront, the POS, merchandising, service, and marketing sit under one brand, so a retailer can buy the catalogue, the till, and the campaign tool from one vendor on one contact record. If you use more than the email part of that, the suite is the argument and it's a real one.

Nitrosend specializes in email, and the surface is the point: every capability is an API endpoint and an MCP tool before it's a screen, so the stack answers to an agent, not a person clicking. Maropost's marketing tool is built for a person in a dashboard, so an agent gets whatever the screen exposes. Pricing follows: the plan is set by what you send, not the contacts you hold, and contacts are unlimited on every plan including Free. Maropost's entry rung is 250,000 contacts at $251 a month on a 12-month term, so the smallest way in isn't small.

Anyone testing a suite against a specialist tends to price Moosend, Omnisend, and Outfunnel on the same list, since all three sell the email half without the storefront attached.

Pricing math

What you actually pay.

Maropost's Marketing Cloud plan is set by the number of contacts you hold, and a send limit sits over the top of it with a per-email overage charge above that limit. The contract runs 12 months, so the rung you pick is the rung you keep. Both ladders below are published and both are in USD, and ours is counted on emails sent.

Scenario	Nitrosend	Maropost
Free	8,000 emails to start, then 500/mo forever. Unlimited contacts, 1 seat, full MCP, API, and CLI	No free plan and no free trial, so the route in is a demo
Entry paid tier	$20 Pro: 20,000 emails, 3 seats, BYO sending and AI keys	Starts at $251 Essential: 250,000 contacts, 5 seats, 5 journeys, and 50 custom contact fields
A list that grows	$100 Ultra: 125,000 emails, 5 brands, 10 seats, and the price doesn't move with the size of the list	$849 Professional: 1,000,000 contacts, 10 seats, 20 journeys. Dedicated IP and a sandbox start on this rung
Scale	$300 Enterprise: 500K to 4M+ emails at a published price, with SSO and SAML	$1,699 Enterprise: unlimited contacts, unlimited seats, unlimited journeys, and relational table data storage

Migration

How to switch (or run both).

Maropost keeps sending while you move, and the storefront, POS, and service work stays exactly where it is.

Add and verify your sending domain in Nitrosend. DKIM and SPF records sit alongside Maropost's, so both platforms send from the same domain for as long as the overlap lasts.
Export your contacts before anything else. In Maropost that's AUDIENCE, then Contact Lists, then Export on the list you want, and a larger move runs over the API or by FTP instead. Import them with nitro_import_contacts.
Start with one low-stakes message type: a receipt or a password reset, sent with nitro_send_message. Maropost carries transactional email on every plan and documents a REST route for it, so there's a direct equivalent to move, and it's the safest thing to watch for a week.
Rebuild journeys as flows with nitro_compose_flow. The triggers have equivalents on both sides: contact added, field changed, and event fired.
Decide what carries your reputation. BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, on the domain you already warmed. Maropost sends through its own infrastructure and isn't one of those five, so what travels with you is the domain and its authentication history.

Honest credit

What Maropost does well.

Maropost's marketing tool arrives already joined to the storefront, the POS, and the service desk, and a retailer running that whole stack gets real leverage out of the join.

One vendor for the storefront, the POS, merchandising, service, and the marketing tool, which removes a stack of integrations for a retailer running all of it.
Cross-channel on one contact record: email campaigns, SMS campaigns, mobile keywords, in-app push, and Meta ads in the same campaign flow.
Transactional email on every plan including Essential, so triggered mail isn't a second product on a second bill.
Journey Builder is visual multi-step automation across email, SMS, and push, with entry rules that fire on real behavior and events.
Prebuilt journeys for the ecommerce lifecycle: welcome, abandoned cart, nurture, advocacy, lapsed buyer, and re-engagement.
eRFM scoring on recency, frequency, monetary value, and engagement, surfacing champions, at-risk, and inactive cohorts automatically.
Contact 360 keeps engagement, purchase history, and list membership in one record, so the profile sits beside the list rather than in a second system.
Deliverability sold as a managed service, with a dedicated deliverability manager from Professional upward.

What Nitrosend adds

Where we think we're better.

Contacts are unlimited on every plan, including Free, so a list that grows without being mailed never moves the bill.
Maropost bills on contacts held rather than campaigns run, so a sender with 5,000 addresses still starts on a 250,000-contact rung.
No annual commitment here, where a Maropost contract runs 12 months and a downgrade waits for the end of the term.
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.
The difference shows at the edges: deliverability, billing, and approvals are MCP tools here, callable by an agent rather than clicked through a dashboard, and they're the ones that usually stop an automation dead.
BYO sending keys on Pro and above route your mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, which makes the move reversible.

Use case fit

When to pick which.

Pick Maropost if

You're already running the storefront and the till on it, and email is one tenant of that contract rather than the program itself. It points the same way if you send SMS and push alongside email and want one bill for all of it, if you'd rather have a named deliverability manager and a customer success manager than a set of docs, or if unlimited contacts, seats, and journeys on one contract is the shape you're buying. None of those are close calls.

Pick Nitrosend if

Email is the channel your program runs on, campaigns and transactional email share one contact record, and your list is much larger than your send volume, so paying by the size of the database has started to hurt. It's the right call too when you'd rather start on a free plan than a 12-month term, or when you want the platform to answer to an agent end to end, including the deliverability, billing, testing, and approval steps that usually send someone back to a dashboard.

Maropost vs Nitrosend - common questions.

Can Nitrosend replace Maropost?

For the email half, yes. Campaigns, flows, segments, templates, contacts, and transactional sending are each an MCP tool and an API endpoint before they're a screen, and transactional isn't a separate product with a separate bill. Maropost keeps the rest of the suite it was built around, so the storefront, the POS, merchandising, service, SMS, and push either stay there or leave with it. Teams using Marketing Cloud only for campaigns, flows, and transactional email are swapping like for like.

What does Maropost cost?

Marketing Cloud is published at three rungs: $251 a month for Essential with 250,000 contacts, $849 for Professional with 1,000,000, and $1,699 for Enterprise with unlimited, all on a 12-month commitment. A send limit sits over the contact tier, with a per-email overage charge above it, and the other four clouds are priced separately. Nitrosend's paid ladder is $20, $100, and $300, counted on emails sent rather than contacts held.

How do I get my data out of Maropost?

Contact lists export from the UI: AUDIENCE, then Contact Lists, then Export on the list you want, with an Encrypted Export option beside it that writes the addresses as MD5 hashes. Anything larger runs over the API or by FTP, and suppression and Do-Not-Mail lists move through Data Journey actions. Export while the account is still live rather than after you've given notice, then import the file with nitro_import_contacts.

When can I stop paying Maropost?

When the contract term ends, not when the migration finishes. Maropost contracts carry a 12-month commitment, and a downgrade only takes effect at the end of the term, so the date is set by the paperwork rather than by the work. There's no term at this end, which is why the usual shape is to start on Free or the $20 rung, run both platforms until the Maropost term runs out, and make the renewal date the cutover.

Start with the free tier.

8,000 emails to start, then 500 a month, unlimited contacts, full MCP, API and CLI access. No credit card.
