From our customer calls.
Leigh Roy, Founder coach“I don’t need to be in Nitrosend. I can just have a conversation through Claude.”
My Speaking ScoreJohn Healy, Founder“Getting all the emails set up through Claude and just not really needing to jump into the UI [...] especially after years of using Mailchimp and [...] Marketo and Salesforce Marketing Cloud, it’s been a boon more than anything.”
Harsh Sanghavi, Growth

Tyler Alfred, Owner

Adam Alamine, Email marketing
“The way you set up the onboarding was awesome. The level of detail.”
Greywolf AgencyMark Smith, Founder“One of the beautiful things that you guys have from an onboarding perspective is you have an MCP server, and that was basically how I validated whether or not your product was going to be good for my business.”
Blake Waldron
“It’s not just using AI as a chatbot. [...] When I saw Nitrosend, that’s how I felt. We are reinventing email marketing finally.”

“It’s definitely better than copy pasting into beehiiv.”

Your Salon SupportBrayden Lee, PartnershipsAgency partner (revenue share)“Just being able to say what you want and have it happen is quite a shift.”
Jacqueline du Plessis, Workshop host
“I’ve tried GoHighLevel four times. When I got to this part, it was just too many clicks and too many steps to just create a flow. So I can’t wait to create a flow through Claude Code.”
TalonKim Stewart, Marketing Manager“This is exactly what I want. Oh my God. It’s picked it up.”
Bartley LegalRhian Bartley, Criminal defence lawyer“I think that will work really well with what you’re doing here and tying that all in via Claude.”

Corey Haines, FounderNitrosend affiliate
“I migrated from MailerLite because I didn’t want another dashboard, and the drag-and-drop builder was so tacky. I just set it up once, and now Claude knows which template to use. My emails are 90% created automatically now. It saves me time.”
Go-to-market for Shopify appsOhad Michaeli, Consultant“[...] your Claude is doing all the routine-based stuff. It kind of goes through and it sends it out and it works beautifully.”

- Verified UserComputer Games10x Better Campaigns with Straightforward Integration and a Breeze-to-Use Email Builder
The campaigns I’ve built with this are easily 10x better than what I would have created on my own, even using AI. It just seems to know what to do and then actually does it.
“I run my email out of Cursor because I do everything else out of Cursor.”

Nitrosend — AI-native email, fully MCP-controlled. Build sequences, campaigns, and automations by prompting. No dashboard.
- Hailey Mason
Co-Founder & CEO at EvattoIt’s so bloody good! EDMs were the bane of my existence before this!
- Garance D.Owner, Small-BusinessLets Me Focus on My Practice
I can focus on what’s most important for my practice without having to understand everything about email marketing.
Santiago@svpinoI’m glad somebody is willing to break the rules and do something different.
We’ve always built for humans and enhanced with AI features. This goes the other direction: build something AI-first, enhance with human features.
Congrats on the launch!
- Mark SmithFounder, Greywolf Agency
Proudly beta user. Easy to work with, and what a team. So quick with updates and fixes for my broken workflows. Well played sir!
- Verified UserInformation Technology and ServicesSpeeds Up Email Creation with AI Ease
I really like Nitrosend for its speed; going from zero to setting up emails is crazy quick.
Krishna Agrawal@KrishnasagrawalWe spent years learning Mailchimp, Klaviyo, ActiveCampaign, HubSpot.
Now people are just typing: “Launch my newsletter.” And the entire workflow happens automatically.
Software is becoming a conversation.
- Ben ArmstrongManaging Partner at Archangel Ventures
Glad to be backing this great team in reinventing one of the most ubiquitous forms of communication at scale.
- Sarah BainbridgeHead of Marketing, Obooko10x faster AI email marketing without logging in
I use Claude to run all my email marketing with Nitrosend. Seriously awesome, 10x faster than how I used to do newsletters as I’m getting AI to compose them, directly into Nitrosend. Their MCP connection means I literally don’t need to login anymore. I’ve got 840K authors and readers so cost of email is important, and it’s affordable too.
Jay Bisen@JayBisen473370Email marketing stops being a tool you operate, and becomes something you simply prompt.
- Thea NgoInvestor, Host of Founders In Motion
The best AI native workflow for the most important modality for anyone to engage with their community.
- John F.Perfect transition from Klaviyo
I love how Nitrosend lives inside Claude; one prompt builds a full email flow. It saves us hours by cutting out the need to drag blocks around in email builders like Klaviyo. The switch from Klaviyo was way smoother than expected, and now, obviously, we don’t want to switch back.
Parul Gautam@Parul_Gautam7Most email tools added AI as a feature. Nitrosend feels like it was built the other way around, AI first, email second.
Creating complete email flows directly from Claude is a glimpse of where agent-native software is heading.
- Renat GabitovFounder at Represent
The email is changing with AI too. Finally.
- Renat G.Founder at RepresentSuper smooth setup
It automatically creates on-brand emails that meet our goals, without the need to manually create a hundred emails or set up triggers. The copy is done really well. The initial setup was super smooth, taking only about ten minutes.
Chidanand Tripathi@thetripathi58The moment I have to open an email builder, I lose all motivation. Nitrosend skips that entire process.
Just describe what you want, Claude builds it, and it’s ready to send.
- Gaurav Thapa
Co-Founder at FastlaneUh oh… RIP Klaviyo 💀💀
- Verified UserVenture Capital & Private EquitySeamless MCP connection, smooth delivery
Connected straight onto my Claude which makes for a good user experience. Support is top notch and it delivers the emails really smoothly, first pass AI is usually already really great. Much cheaper than Klaviyo.
Arsalan@AIwithArsalanRemoving the dashboard entirely and turning email marketing into a simple conversation with Claude.
Charles Roman@pumpkhermOne prompt replacing an entire email workflow is a powerful idea.
Sripathi Teja@sripathiteja4Most AI email tools give you emails that feel generated. Nitrosend creates emails that look exactly like your brand, stay fully editable, and land in inboxes reliably.
FELIX@FellMentKEBuilding email flows has always been the worst part of growth.
Nitrosend letting you one shot entire campaigns from Claude with pixel perfect design is the hostage rescue we needed.
Don Quijote de la IA@IA_QuijoteImagine a MailChimp inside Claude.
You just describe it and emails are created with flawless branding images.
Case studies
The numbers behind the switch.
Game changer.
I run Nitrosend through Claude to do my outbound marketing emails. The free plan is great but the biggest delta for me is the huge time saving. Before Nitrosend I didn’t have time to regularly email my customers, it was ad-hoc.

Why I switched from Campaign Monitor to Nitrosend.
“The best email platform in the world is useless if the friction stops you from using it.”
I run ADB Magazine, Australia’s biggest dirt bike mag, going since 1975. I inherited Campaign Monitor at $300 a month. They charge by subscriber count, so whether I sent ten newsletters or zero, the bill was the same. Spending 45 to 60 minutes in a drag-and-drop editor to build each send didn’t help. Some months I’d send nothing. Still paid $300.
- $300 → $100
- Monthly cost
- 60 → 5 min
- Time to compose
- 40x+
