Sequenzy

Sequenzy is an email marketing platform built for SaaS companies. It sends campaigns, automated sequences and transactional email from one account, and it prices by the number of emails you send rather than by the number of contacts you store. The homepage headline is "Powerful email marketing. Without the complexity or per-contact pricing," and the subhead sums up the product: "Campaigns, automations and transactional email from one account, triggered by your product and Stripe. AI writes it. Your agent can run it." The footer names the company behind it as Nic Tech Solutions, LLC, registered in Delaware, and carries the line "Made in Ukraine."

What a sender gets

The homepage explains that transactional mail, campaigns and automations "share one contact list, one set of templates, one sending domain and one revenue report."

Transactional email covers receipts, password resets and invoices. It goes out through "One call to the REST API or the SMTP relay," uses the "Same templates and sending domain as everything else," and is "Delivered in seconds, tracked like every other send."

Campaigns can go to the whole list or to a segment built from plan, MRR and last activity. Subject line A/B tests "pick their own winner," and each email is sent at each subscriber's best hour and reported in revenue.

Automations run on events. A flow can be started by Stripe, PostHog or a POST from your own backend, with branches, delays and conditions, and the homepage says "Dunning, win-back, onboarding and upsell run on their own." Its examples show the idea: a failed Stripe payment starts a dunning flow with a card-update page, a canceled subscription starts a win-back on day 3, and an account hitting its usage limit gets an upsell. Segments combine plan, MRR and engagement data, for example Pro customers paying $99 or more who have not opened an email in over 30 days.

Revenue attribution is a big part of the pitch. The homepage says "Every send is tracked to delivery, reply and revenue through your billing, not last-click guesses," with revenue broken down by flow, campaign and individual email, plus goals, A/B testing, send-time optimization and automatic UTM tags.

AI and agents

Sequenzy leans hard on AI. Enter your website and it writes full sequences, "the trigger, the timing, every subject line and the copy behind it," and it adapts the design to your brand, pulling logo and palette from the site; every block stays editable in the block editor. The homepage says setup with AI from your URL takes "2 min." Localization is listed among the writing tools.

It calls itself agent-native: "Every feature is a tool for Claude, Cursor, Codex and Claude.ai through MCP, and for your code through the CLI and REST API." A remote MCP server with OAuth offers what the page counts as 200+ tools, and a CLI installs from npm. The agent can build a segment, write the emails and publish a landing page, but "Nothing sends until you approve it." The developer section lists docs, a TypeScript SDK, a Better Auth plugin and GitHub.

Other features and integrations

Beyond email, the "everything else" list includes landing pages, forms and popups, SMS and MMS, a team inbox, reply tracking, webhooks, analytics and deliverability tools, out of what the site calls "All 45 features." Integrations number 16, "including Stripe, Shopify, Paddle, Clerk, Supabase and PostHog," and the pricing section lists payment integrations with Stripe, Paddle and Lemon Squeezy.

Pricing and plans

The pricing section is titled "Priced per email. Never per contact." and promises "Every feature on every plan." The free tier covers 2,500 emails a month, and a pricing guide on the Sequenzy site lists the paid tiers by monthly volume: $19 for 15k emails, $29 for 30k, $49 for 60k, $99 for 120k, $199 for 300k, $399 for 600k, $599 for 900k, $799 for 1.2M, $1,299 for 2M, $1,999 for 3M, $2,499 for 4M and $2,999 for 5M, with custom pricing for unlimited volume. The same guide says "All plans offer a 10% discount when billed annually."

Every plan includes unlimited contacts, "No daily email limit," the visual automation builder, the transactional email API, reply tracking and a team inbox, unlimited team members, unlimited lists and segments, API, MCP and CLI access, unlimited sending domains, SPF, DKIM and DMARC, deliverability monitoring, send time optimization, A/B testing, no "Sent with Sequenzy" watermark and "Personal founder support." The homepage pricing list includes one landing page. The FAQ confirms that marketing and transactional mail share "the same account and pooled email allowance," and that "Growing your list does not move you to a higher plan by itself."

Deliverability, data and migration

On deliverability the FAQ says you "Authenticate your sending domain with SPF, DKIM and DMARC, track bounces and complaints, and monitor sender reputation." It adds that "Dedicated IP options are available on paid plans," with setup discussed based on volume. To get data out, you use the REST API for subscribers and reporting and webhooks for "delivery, open, click, bounce and unsubscribe events." The footer links to a DPA.

Migration is free and hands-on. Sequenzy says it moves "subscribers, tags, sequences and templates for you and map your segment rules, with your active flows kept running," and names Klaviyo, Mailchimp, Customer.io, Loops, ActiveCampaign, Brevo and ConvertKit as platforms it moves customers from. Scope, including customers partway through a flow, is confirmed on a migration call.

The homepage shows 4.9 stars on G2. Its customer stories include SnapCount, whose founder says "Migration was done in 24 hours without any issues," Moxie Docs, which wired six product events into nine lifecycle flows in one afternoon, and InstantInterior AI, which reports $600 revenue in 30 days from email automations.

Who it suits

Sequenzy fits a SaaS founder or small product team that bills through Stripe or Paddle and wants onboarding, trial conversion, dunning, win-back and product emails in one place, with revenue tracked per email. Because pricing follows sending volume, a team with a big list of free users that it emails rarely pays for sends, not for stored contacts. Developers and anyone working through Claude, Cursor or Codex will find the MCP server, CLI and API central rather than bolted on.

A business outside software can still use it, and the site has pages for dentists, restaurants and real estate, but the event triggers, MRR segments and billing integrations that set Sequenzy apart assume a subscription product behind the list.
