01 · Every email

Every email you send, from one account.

Transactional, campaigns and automations share one contact list, one set of templates, one sending domain and one revenue report.

Transactional
API · SMTP

Receipts, resets and invoices

  • One call to the REST API or the SMTP relay
  • Same templates and sending domain as everything else
  • Delivered in seconds, tracked like every other send
TransactionalSMTP
$POST /v1/transactional/send
Campaigns
one-off

One email to millions, or to one segment

  • Send to your whole list or a segment from plan, MRR and last activity
  • Subject line A/B tests pick their own winner
  • Sent at each subscriber's best hour, reported in revenue

Automations
event-driven

Flows that run on events

  • Started by Stripe, PostHog or a POST from your backend
  • Branches, delays and conditions, no rules to hand-write
  • Dunning, win-back, onboarding and upsell run on their own

02 · Revenue-triggered

Triggered by what happened, not by guesswork.

Connect Stripe or PostHog once, or send your own events with one POST. Each event starts the right flow for a segment built from plan, MRR and engagement data.

All 45 features

06 · Agent-native

Tell your agent what the campaign should do. Approve it. It sends.

Every feature is a tool for Claude, Cursor, Codex and Claude.ai through MCP, and for your code through the CLI and REST API. The agent builds the segment, writes the emails and publishes the page. Nothing sends until you approve it.

“$600 revenue in 30d from email automations. Very happy I migrated to Sequenzy. Before I was making zero from email automations.”
Max Eccles · Founder, InstantInterior AI
“The best part is that Sequenzy is AI native, I rarely do stuff in the dashboard, just use my AI to create campaigns, sequences and segment customers which saves me a ton of time. Never been happier with an email marketing tool.”
Filip Panoski · Founder, Bazzly
“Migration was done in 24 hours without any issues, and I can run all of my products from a single account.”
Viraj · Founder, SnapCount

FAQ

Questions, answered.

Does the price go up when my audience grows?

Plans are based on email sending volume, with unlimited contacts and every feature included. Growing your list does not move you to a higher plan by itself. Choose the sending allowance that covers your campaigns, automated flows and transactional emails.

Can I send marketing and transactional email from one account?

Yes. Send campaigns and automated sequences to your audience, and send receipts, password resets and other account emails through the transactional API or SMTP. They use the same account and pooled email allowance.

Can I bring my existing sequences and segments?

Import subscribers and tags by CSV or API. We help recreate sequences and templates, and review how your existing segment rules map to Sequenzy. Confirm the scope on your migration call, including customers already partway through a flow.

How do we switch without disrupting active flows?

Start by mapping your active sequences, event sources and sending schedule. On the migration call, we will agree the order of the move, what needs testing, and how to handle in-flight customers. Timing depends on your setup.

Can I keep using my API workflows and AI tools?

Use the REST API and CLI for subscriber management, campaigns, sequences and reporting. Connect your AI tools through MCP to work with the same account. Your existing integration code will need to use Sequenzy's endpoints and event formats; review those mappings as part of the move.

How do you handle deliverability at volume?

Authenticate your sending domain with SPF, DKIM and DMARC, track bounces and complaints, and monitor sender reputation. Dedicated IP options are available on paid plans; contact us to discuss setup for your volume.

Can I get my data out?

Use the REST API to retrieve subscribers and reporting data, and webhooks to send delivery, open, click, bounce and unsubscribe events to your own systems.
