Nitrosend vs Drip.

Billed on what you send, not who you keep. Unlimited contacts, and agent-native.

TL;DR

Drip is ecommerce marketing automation. Email, onsite popups and embedded forms, and segmentation built directly on storefront data sit in one product on one plan, with no feature tiers: everything is switched on from the first paid rung and the price moves only with the size of your list. If your program is a store's lifecycle and you send often to a list that doesn't grow much, that model pays you back.

Nitrosend specializes in email: an AI-native email platform, priced the other way round. Contacts are unlimited on every plan, including Free, so the bill follows what you sent rather than who you kept, and every capability is an API endpoint and an MCP tool before it's a screen. The meter decides the money, because Drip bills on active people and an unsubscribed person is still an active person. What decides the workflow is whether you can run the whole stack from one agent command. Stores weighing this usually read it next to our Emailchaser comparison, the EmailOctopus one, and the Emarsys one, and the rest sit on the full comparison index.

Pricing math

What you actually pay.

Drip's rungs are counted in active people, so the two ladders below are measuring different things. Unsubscribed people are still active people, which means they stay on the bill after they stop being mailable. Billing also runs on a high watermark, so the highest count the account held at any point in a cycle sets the price for that cycle.

Scenario	Nitrosend	Drip
Free	8,000 emails to start, then 500/mo forever. Unlimited contacts, 1 seat, full MCP, API, and CLI	No free plan. A 14-day trial capped at 2,500 contacts and 100 total sends
Entry paid tier	$20 Pro: 20,000 emails, 3 seats, BYO sending and AI keys	$39 from 2,500 active people, with automation, segmentation, and reporting on from the first rung and unlimited users on the account
10,000 people on the list	$20 Pro still: 20,000 emails at any list size, because contacts are unlimited	$154 at 10,000 active people, whether or not you can mail them
Scale	$100 Ultra: 125,000 emails, 5 brands, 10 seats. $300 Enterprise: 500K to 4M+ emails at a published price, with SSO and SAML	Monthly send limits begin above roughly 32,500 subscribers, and the published ladder ends at its top rung and goes quote-only above it

Migration

How to switch (or run both).

Drip keeps sending while you move, and the onsite popups and embedded forms stay exactly where they are until you have a replacement capture route.

Add and verify your sending domain in Nitrosend. DKIM and SPF records sit alongside Drip's, so both platforms can send from the same domain for as long as the overlap lasts.
Export your people with their tags and custom fields, and import them with nitro_import_contacts. Tags map onto lists and segments, and custom fields map onto custom fields, so the shape survives the trip. This is also the moment to leave the unsubscribed behind, because they were billable at Drip and they carry nothing forward.
Move one message type first: a receipt or a shipping notice, sent with nitro_send_message. Watch it for a week before a campaign follows it.
Rebuild workflows as flows with nitro_compose_flow. The triggers have equivalents on both sides: person added, tag applied, custom field changed, and event recorded.
Decide what carries your reputation. BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, and Drip's own pool isn't one of them, so a sender leaving Drip is warming a new path whichever platform they land on. What travels with you is the domain and its authentication history.

Honest credit

What Drip does well.

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

Unlimited email sends on every published rung up to roughly 32,500 subscribers, where plenty of platforms ration sends by list size.
No feature gating between rungs: automation, segmentation, and reporting are on from the first paid rung, and the price moves only with the list.
Unlimited users on the account, so team size never prices anyone out.
Onsite popups and embedded forms are part of the product rather than a second subscription.
Segmentation built directly on storefront customer data rather than on fields you imported yourself, with Shopify, WooCommerce, and BigCommerce as the named integrations.
A/B split testing inside automation workflows, not only on one-off broadcasts.
A documented REST API reaching subscribers, campaigns, broadcasts, workflows, tags, events, orders and carts, products, conversions, forms, and webhooks.
Official client libraries for Ruby and Node, with published rate limits and batch endpoints carrying up to 1,000 records each.

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.
Our meter is what you sent, so neither an unsubscribed contact nor a one-off acquisition spike moves the bill, where Drip prices a cycle on the highest active-people count it held.
A published price from 500,000 to over 4,000,000 emails a month, where Drip's ladder adds send limits above roughly 32,500 subscribers and goes quote-only above its top published rung.
A free plan a real sender can start on, against a 14-day trial capped at 100 total sends.
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.
Our MCP surface is first-party and moves on our own release schedule, where the Drip MCP servers in circulation are third-party wrappers over its REST API, maintained by other people.
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, which makes the move reversible.

Use case fit

When to pick which.

Pick Drip if

You run a store and the program is the store's lifecycle, and you want popups, forms, and segmentation on storefront data in the same tool that sends. It points the same way if you mail often to a list that doesn't grow much, which is exactly the case a fixed contact count with unlimited sends pays back. Nitrosend has no first-party ecommerce app with product-feed sync, so if a storefront integration is the requirement, this isn't a close call.

Pick Nitrosend if

Email is the channel your program runs on, and your list is much larger than your send volume, so paying for people you can't mail has started to hurt. It's the right call too when transactional email and campaign belong in one product, or when you want the platform to answer to an agent end to end, including the billing, testing, and approval steps that usually send someone back to a dashboard. Same answer for SaaS, creator, and B2B senders, who usually get handed a shortlist of ecommerce tools.

Drip vs Nitrosend - common questions.

Can Nitrosend replace Drip?

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. Drip tags map onto lists and segments, and custom fields come across as custom fields. Onsite popups, embedded forms, and storefront-data segmentation are Drip features and they stay with Drip, so a store using them to capture addresses needs a replacement capture route first.

Why is my Drip bill higher than the list I actually mail?

Because it's billed on active people. An unsubscribed person is still an active person, so they keep their place on the bill after you're no longer allowed to mail them, and billing runs on a high watermark, which means the biggest number you held at any point in the cycle sets the price for that cycle. Contacts are unlimited on every Nitrosend plan, including Free, so the same list costs nothing to hold.

Does Drip have an MCP server?

The Drip MCP servers in circulation are third-party wrappers over Drip's REST API, and the other route in circulation is a generic hosted connector, which puts a third party between the agent and the account. Nitrosend was built the other way round: every capability is an API endpoint and an MCP tool before it's a screen. The practical test is the edges, where deliverability, billing, tests, and approvals are tools here rather than screens.

Does team size change the bill on either side?

On Drip, no: users are unlimited on the account, so a team that all works in the dashboard never pays for the extra logins. On Nitrosend, seats are counted: 1 on Free, 3 on Pro, and 10 on Ultra. What changes the arithmetic is what a seat is for, because the sending, the tests, and the approvals run through the API and MCP rather than through somebody's login.
