Nitrosend vs QuickMail.

Lifecycle email, MCP and API on every plan, unlimited contacts, published price.

TL;DR

QuickMail is a cold outreach platform. It sends from the mailboxes you connect, rotates across them, warms them for free, runs LinkedIn steps in the same sequence as the email ones, and lands every reply in one inbox. Senders, LinkedIn accounts, and users are unlimited at every rung. If your job is cold outbound, it does that job, and this page isn't going to argue otherwise. It is the clearest example of a category difference running through our comparison index.

Nitrosend is a different product, for the email that starts once a prospect answers. Every capability is an email API endpoint and an MCP tool before it's a screen, so the whole stack answers to one agent command. Campaigns, flows, segments, and transactional sends sit in one platform. Contacts are unlimited on every plan including Free, and BYO sending keys are there on Pro and above. A team whose whole email program is cold outbound wants QuickMail. Most teams end up running both.

Pricing math

What you actually pay.

The two ladders meter different things. QuickMail bills on emails sent and on contacts uploaded, and both caps step together at each rung, while Nitrosend bills on emails and leaves contacts unlimited. Both columns are monthly, in USD. Pick the row closest to your scale.

Scenario	Nitrosend	QuickMail
Getting started	Free: 8,000 emails to start, then 500/mo forever. Unlimited contacts, full MCP, API, and CLI	14-day trial on every plan, card required at signup. No permanent free sending tier, though the warm-up is free on every paid plan
Entry paid rung	$20 Pro: 20,000 emails, unlimited contacts, 3 seats, BYO sending and AI keys	$49 Starter: 5,000 emails, 1,000 uploaded contacts, unlimited senders, LinkedIn accounts, and users, 1 workspace
The first rung with an API	Free: the MCP, REST API, and CLI are on every plan, so there's no rung to climb for one	$99 Growth: 100,000 emails, 25,000 uploaded contacts, and the first rung that carries API access
500,000 emails/mo	$300 Enterprise: 500K to 4M+ emails at a published price, with SSO and SAML	$299 Agency: 500,000 emails, 100,000 uploaded contacts, 2 workspaces, webhooks, and $49 for each workspace after that

Migration

How to switch (or run both).

Most teams here don't switch: they add. QuickMail keeps the cold outbound, Nitrosend picks up everything after the reply, and the two can share a domain for as long as you like.

Add and verify your sending domain in Nitrosend. DKIM and SPF records sit alongside whatever your outbound mailboxes already use, so both can send from the same domain during the overlap.
Leave the cold outbound where it is. QuickMail keeps running the sequences, the inbox rotation, the free warm-up, the LinkedIn steps, and the unified reply inbox, and for most teams that never becomes a cutover.
Move the prospects who answered. Import them with nitro_import_contacts; email, first and last name, and custom properties map across. The $49 Starter rung carries no API, so the CRM sync or Zapier is the route out of it.
Build the sequence that starts after the reply as a flow with nitro_compose_flow. Onboarding, nurture, and product notifications. QuickMail has no flow builder over an owned contact database, so this is usually the first time that sequence has existed as one object.
Decide what carries the sending. BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, and QuickMail isn't one of them. Your domain and its authentication history travel with you, so it's reversible.

Honest credit

What QuickMail does well.

Picking a tool is about fit, and QuickMail is good at a job Nitrosend doesn't do.

Free inbox warm-up on every plan including the $49 rung, delivered through a native MailFlow integration rather than sold as an add-on.
The warm-up carries no volume cap, so the number of inboxes being warmed never moves the bill.
Unlimited email senders and unlimited LinkedIn accounts on every plan, including the entry rung.
Unlimited users on every plan, so the size of the team never changes the price.
Email steps and LinkedIn steps run in one sequence, with connection messages, InMail, and voice messages available as step types.
One unified inbox collects replies from email and LinkedIn together instead of splitting them by channel.
Inbox Rotation spreads a campaign's sends across every connected sender automatically.
Deliverability AI watches sender performance and swaps out an underperforming account without being asked.
Native two-way sync with HubSpot and Pipedrive, rather than a one-way push through a third-party connector.
Google Workspace mailboxes can be bought and configured inside the product at $3 a month, which takes the DNS setup off you.
Zapier is included from the entry rung up, so an account with no API still has an automation route.

What Nitrosend adds

Where we think we're better.

Campaigns, flows, segments, and transactional sends in one platform, for the email that starts once a prospect has answered.
Unlimited contacts on every plan, including Free, so a list that grows without being mailed never moves the bill.
MCP-first is an architecture, not an integration: every capability is an API endpoint and an MCP tool before it's a screen.
The MCP, the REST API, and the CLI are on every plan, including Free.
The MCP covers campaigns, flows, contacts, templates, and segments, not a read-only slice of them.
Deliverability, billing, tests, and approvals are tools too, and they're the four that usually stop an automation dead.
Bounce and complaint events are objects the same agent can read, not a dashboard somebody has to go and look at.
Events, suppression, and exports are objects in their own right, with the same coverage as everything else on the platform.
Transactional sends deliberately 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 you already warmed.
A published price from 500,000 to over 4,000,000 emails a month, where a ladder this long usually turns into a sales call.

Use case fit

When to pick which.

Pick QuickMail if

Your email is cold outbound to people who have never heard of you. You need sends rotating across mailboxes you connect, with warm-up running behind them, LinkedIn steps in the same sequence as the email ones, and every reply from both channels landing in one inbox. You're adding senders and teammates constantly and don't want either to move the price. You run outbound for clients and want workspaces keeping them apart. None of those are close calls.

Pick Nitrosend if

Your email goes to people who already know you, and you want campaigns, flows, and transactional sends in one place. It's the right call when you want the whole platform drivable by the agent you already run, on every plan rather than from a rung up, or when you're tired of a contact count moving your bill and want a published price at the top of the ladder. The sharpest case is a team already running outbound somewhere, with nowhere sensible for everything after the reply. Anyone weighing the outbound tools against each other should read Salesforge and Saleshandy alongside this one, and Resend if the developer-side sending matters more than the sequencing.

QuickMail vs Nitrosend - common questions.

Can Nitrosend replace QuickMail for cold outreach?

No. Nitrosend never touches your mailboxes, and connected mailboxes are what cold outreach runs on. What it does replace is everything after the reply, which is where a cold outreach tool stops: campaigns, flows, segments, and transactional sends against a contact list you own, run from one agent command rather than from a screen.

What does QuickMail actually cost?

Three published rungs, billed monthly: $49 Starter, $99 Growth, and $299 Agency. Each rung raises two ceilings at once, one on the emails you send and one on the contacts you've uploaded, so a list growing faster than your sending can push you up a rung on its own.

Does Nitrosend or QuickMail have a free plan?

Nitrosend does. The Free plan opens with 8,000 emails and settles at 500 a month, contacts aren't counted at all, and the MCP, the REST API, and the CLI come with it. QuickMail doesn't sell one: you get 14 days on whichever plan you choose, a card goes in at signup, and the only thing that stays free afterwards is the inbox warm-up, which has no volume cap.

What's involved in moving from QuickMail to Nitrosend?

Less than a migration usually, because the two jobs don't overlap. Cold outbound carries on where it is, Nitrosend takes over once a prospect answers, and nothing has to be switched off on a date. The two pieces of real work are verifying your sending domain and building the first post-reply flow. Getting the contacts across is the easy half: a bulk import, the HubSpot or Pipedrive sync, or Zapier.
