Nitrosend vs Dotdigital.

Built for email, agent-native, unlimited contacts, and a price published at every rung.

TL;DR

Dotdigital is a cross-channel marketing automation platform. Email, SMS and MMS, WhatsApp, mobile push, web personalization, and ads sit on one contact record with a customer data platform under them, sold to mid-market and enterprise retail through a demo and a quote. If you use more than the email part of that, the platform is the argument, and it's a real one.

Nitrosend specializes in email, and we priced and built it the other way round. The number is published at every rung, contacts are unlimited on every plan including Free, and every capability is an API endpoint and an MCP tool before it's a screen. Dotdigital has shipped a real MCP server and two in-product AI agents, so the difference isn't whether the other one has an agent surface. It's what each one was built over.

Retail teams at this end of the market usually shortlist the ecommerce-native tools too, so the Drip comparison and the EmailOctopus comparison bracket the range on price, and the Emailchaser comparison covers the outbound end of it.

Pricing math

What you actually pay.

Dotdigital publishes no rate card and prices each client on the allowances written into a Service Agreement, so the right-hand column names what the quote is counted on rather than a number. The count is marketable contacts rather than emails sent, and SMS and WhatsApp are usage-based on top of it, billed monthly in arrears.

Scenario	Nitrosend	Dotdigital
Getting started	8,000 emails to start, then 500/mo forever. Unlimited contacts, 1 seat, full MCP, API, and CLI	No published plan and no self-serve price. The route in is a demo and a quote
Entry paid tier	$20 Pro: 20,000 emails, 3 seats, BYO sending keys	Quoted on marketable contacts and message volume, with contact, message, and Insight data allowances set in the agreement
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	Billed on the highest marketable contact count in the period, so the invoice tracks the database rather than the campaign calendar
Scale	$300 Enterprise: 500K to 4M+ emails a month at a published price, with SSO and SAML	Still a quote. Overage runs at the rates in the agreement, and web personalization page views over the allowance at 125% of base cost

Migration

How to switch (or run both).

Dotdigital keeps sending while you move, and the SMS, WhatsApp, and web personalization work stays exactly where it is.

Add and verify your sending domain in Nitrosend. DKIM and SPF records sit alongside Dotdigital's, so both platforms send from the same domain for as long as the overlap lasts.
Export your contacts first, and do it while the account is live. An account's data is deleted 90 days after a contract ends. Import them with nitro_import_contacts.
Start with one low-stakes message type: a receipt or a password reset, sent with nitro_send_message. Dotdigital reaches those through the Communications part of its API, so there's a documented equivalent to move, and that transactional email stream is the safest thing to watch for a week.
Rebuild programs as flows with nitro_compose_flow. The triggers have equivalents on both sides: contact added, data 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. Dotdigital 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 Dotdigital does well.

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

Cross-channel against one contact record: email, SMS and MMS, WhatsApp, mobile push, web personalization, and ads.
A customer data platform underneath it, so behavioural and transactional records sit beside the contact rather than in a second system.
200+ integrations, with Adobe, Shopify, Salesforce, Microsoft, and BigCommerce among them.
No limit on the number of users on an account, so a large marketing team isn't rationed by seats.
Two AI agents in the product and generally available: a Segment Agent that builds a segment from a plain-English description, and a Content Agent that writes on-brand copy in the editor.
A real MCP server reaching the account itself over OAuth 2.0, so ChatGPT, Claude, or Gemini can check results or add a contact to a list without opening the platform.
Industry engagement benchmarks exposed as a tool, so an agent can compare a campaign against the sector without running a report.
A second MCP server on the developer hub that serves the OpenAPI specs and the docs to a coding agent.

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.
Dotdigital counts the bill on the highest number of marketable contacts in the period, so the invoice tracks the size of the database rather than the campaigns you ran.
Cleaning that list mid-period doesn't help: a contact deleted or suppressed after it was sent to still counts, and suppressing at list level never removes it.
Every rung of our price is published, including 500,000 to over 4,000,000 emails a month, where the number otherwise arrives in a quote.
MCP-first is an architecture, not an integration: every capability here is an email API endpoint and an MCP tool before it's a screen.
Dotdigital's MCP server covers account details, contacts and lists, campaign metrics, benchmarks, and forms, and it's in public preview behind an account setting.
Its contact tool needs a list or a segment, so an agent can't search the whole base, and Insight and campaign engagement data are out of scope.
The difference shows at the edges: deliverability, suppression, billing, tests, and approvals are tools here, and they're the ones that usually stop an automation dead.

Use case fit

When to pick which.

Pick Dotdigital if

Your program runs on more than email and you want SMS, WhatsApp, push, and web personalization against one contact record. It points the same way if you need a customer data platform holding behavioural records rather than a list, if you're on Adobe, Salesforce, Microsoft, or BigCommerce and want a vendor whose integration was built for it, or if procurement expects a contract, an account team, and unlimited users across a large marketing organisation. None of those are close calls.

Pick Nitrosend if

Email is the channel your program runs on, and the list is much larger than the send volume, so being billed on people you didn't message has started to hurt. It's the right call too when you want to read the price before a sales call, 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.

Dotdigital vs Nitrosend - common questions.

Can Nitrosend replace Dotdigital?

For the email half, yes. Campaigns, flows, segments, templates, contacts, and transactional sending are all here, and transactional isn't a separate product with a separate bill. What doesn't come across is the rest of what Dotdigital was bought for: SMS, WhatsApp, mobile push, web personalization, and the customer data platform under them. Those either stay on Dotdigital or leave with it, so the switch is a scope decision before it's a pricing one.

What does Dotdigital cost?

It's quoted rather than published. The quote is built on marketable contacts plus message volume, with contact, message, and Insight data allowances written into the Service Agreement and overage charged at the contract rate. SMS and WhatsApp run on usage and are billed monthly in arrears on top of that. Nitrosend's ladder is published at every rung, from Free through $20 Pro and $100 Ultra to $300 Enterprise, with contacts unlimited on all of them.

Dotdigital has an MCP server. What's actually different?

Order of construction, and what the server reaches. Dotdigital's covers account details, contacts and lists, campaign metrics, industry benchmarks, and form activity. It's in public preview behind an account setting, and contact retrieval is scoped to a named list or segment rather than the whole base. We built endpoints and tools before we built screens, so the test is the edges: deliverability, suppression, billing, tests, and approvals are all tools here.

How do I get my data out of Dotdigital?

Audience, then Contacts, then Export all, run by the account owner or by a user holding both the Contacts and Contact exporter permissions. You get CSV for contact data fields and one JSON file per collection for Insight data. The files sit under Settings, General, Exports for seven days and then expire, and an account's data is deleted 90 days after a contract ends, so run the export while the account is live.

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.
