Nitrosend vs B2B Hero.

Lead generation and letters on one side, lifecycle and transactional email on the other.

TL;DR

B2B Hero is a German platform for winning new B2B customers. It finds companies in the German commercial register, qualifies them with AI against criteria you set, and reaches them by postal letter, by email, or by phone, with a CRM behind it. Pricing starts at 199 EUR a month plus VAT, metered on record credits rather than sends. If that's the job in front of you, it does it.

Nitrosend is a different product: an AI-native email platform for campaigns, flows, segments, and transactional email, where every capability is an API endpoint and an MCP tool before it's a screen, with unlimited contacts on every plan including Free. It's the email that runs after somebody already knows who you are, and you run it from an agent command rather than a dashboard. Nitrosend can't replace B2B Hero and doesn't try to, because it holds no lead data and sends no letters.

Pricing math

What each one charges for.

These two meter different things, so nothing here converts into a saving. B2B Hero bills monthly credits for company and contact records, in EUR excluding German VAT, with letters at 1 EUR each on top. Nitrosend bills emails sent, in USD, with contacts unlimited. Read each row as a question you're answering, not as a like-for-like rung.

Scenario	Nitrosend	B2B Hero
What the meter counts	Emails sent. Contacts are unlimited on every plan, so list growth never moves the bill	Company credits and contact credits, allocated monthly. The meter counts records revealed rather than messages
Starting free	Free plan: 8,000 emails to start, then 500 a month forever, with unlimited contacts and the full MCP, API, and CLI	Demo: 50 company credits and 50 contact credits, no card and no expiry date. Email mailbox integration isn't included at this level
Entry paid plan	$20 Pro: 20,000 emails, unlimited contacts, 3 seats, BYO sending and AI keys	Starter, 199 EUR a month plus VAT: 1,000 company credits and 1,000 contact credits, with postal mail at 1 EUR a letter
Sending email at all	Included from Free upward	Email mailbox integration starts on Business, 299 EUR a month plus VAT, which also carries 2,000 credits of each kind, AI analysis, and contact download

Migration

How to move what you have.

This is a partial migration, not a cutover. B2B Hero keeps finding companies and posting letters. What moves is the contacts who replied, and everything you send them afterwards.

Export the contacts you've earned. B2B Hero's contact download is a CSV and it's available on the Business plan and above. Pull the companies and people who actually replied out first, because that's the list Nitrosend has a job for.
Leave the prospecting where it is. B2B Hero keeps sourcing companies, running the AI qualification, and posting the letters. None of that job moves, and for most teams it never becomes a cutover.
Verify your sending domain in Nitrosend. Add it, then publish the DKIM and SPF records. Your domain and its authentication history are the one asset that genuinely travels, and they sit alongside whatever mailbox B2B Hero already sends from.
Import the repliers with nitro_import_contacts. Email, first and last name, and custom properties map across from the CSV. If those people already sit in a CRM, that's the cleaner source of the two.
Compose the flow itself with nitro_compose_flow. Onboarding, nurture, product notifications, and the transactional mail alongside them, all built on the contacts you just imported. BYO sending keys on Pro and above route it through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, which is what makes the decision reversible.

Honest credit

What B2B Hero does well.

Picking a tool is about fit. Here's what B2B Hero is genuinely good at.

Postal mail as a first-class automated channel: letters go out at 1 EUR each.
German commercial register data: company sourcing runs on North Data, which is deeper German firmographic coverage than the LinkedIn-derived databases this category usually ships.
One product for the whole outbound motion: sourcing, qualification, post, email, phone, and a CRM, so a German SME buys one tool instead of four.
AI qualification that reads the web: it scores a company against criteria you set by reading its website, rather than filtering on static firmographic fields.
AI-personalised email as a real mode: each lead gets an individually written message instead of a fixed template with merge fields in it.
Data protection positioning with something behind it: German company data, a German operating entity, and German hosting, in a market where buyers ask.
Free credits with no expiry date: 50 company and 50 contact credits sit there until you use them, so evaluating the product isn't a countdown.
Support that arrives as a person: personalised onboarding sessions are standard, and named phone and email support sits on the top plan.
A built-in CRM: pipeline management, activity tracking, and calendar sync, so replies land where the seller already works.

What Nitrosend adds

What Nitrosend is for.

Campaigns, flows, segments, and transactional sends in one platform: one contact base under all four, so a team running both marketing and transactional stops reconciling two sets of analytics.
Unlimited contacts on every plan, including Free: a list that grows without being mailed never moves the bill, so storing people costs nothing.
MCP-first as an architecture, not an integration: every capability is an API endpoint and an MCP tool before it's a screen.
An agent surface over the whole platform: campaigns, flows, contacts, templates, and segments, rather than a read-only slice of any of them.
Deliverability, billing, tests, and approvals are tools too: they're the four that usually stop an automation dead.
The numbers are readable by the sender: complaint rate, bounce split, and domain reputation all come back to the same agent that sent the mail.
Transactional sends stay on the REST API: a send that has to be fast shouldn't wait on a tool call.
A clean REST API and a CLI alongside the MCP: nobody is forced through an agent to get work done.
BYO sending keys on Pro and above: route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, on a domain you already warmed, which is what makes a platform decision reversible.

Use case fit

When to pick which.

Pick B2B Hero if

You sell to German companies and you need to find them before you can mail them. Letters in the post are a channel you want running alongside email, the German commercial register is where your prospect data should come from, and you'd rather have the sourcing, the qualification, the outreach, and the CRM in one place. German-language software and German data handling matter to your buyers or to your compliance team, and you don't want an API anywhere near this.

Pick Nitrosend if

Your email goes to people who already know you, and you want campaigns, flows, and transactional sends in one place. You want the whole platform drivable by the agent you already run, down to deliverability, billing, and approvals. A contact count moving your bill has stopped being acceptable, and you want the transport to stay yours while the platform above it changes. The clearest case is a team already running German outbound somewhere, with nowhere sensible for everything that happens after the reply.

B2B Hero vs Nitrosend - common questions.

Which B2B Hero is this page about?

The one at b2b-hero.com, a German platform for finding and contacting new B2B customers, operated by B2B Hero GmbH in Braunschweig. An unrelated freelance marketing marketplace trades under a similar name, and this page isn't about that one. Everything here refers to the German software.

Can Nitrosend replace B2B Hero?

No, and we don't try to. Nitrosend runs the half that starts once somebody is already in your contact base: nurture, onboarding, product notifications, and transactional sends. Finding companies and posting letters is B2B Hero's front half, and that half has no equivalent here, because we work a contact base rather than a prospect list.

What does B2B Hero cost?

Starter is 199 EUR a month, Business 299 EUR, and Pro 499 EUR, all excluding German VAT. The meter is monthly company credits and contact credits rather than sends, and postal letters are 1 EUR each on top. Email mailbox integration starts on Business, and the CRM is 35 EUR a month extra below Pro.

Is there a free plan on either one?

Both, in different shapes. Nitrosend's Free plan sends 8,000 emails to start and 500 a month after that, with unlimited contacts and the full MCP, API, and CLI. B2B Hero's demo gives 50 company credits and 50 contact credits, with no card required and no expiry date on the credits.
