Change it yourself, or just ask.

Drag blocks and click any text to edit it, in an editor that shows the email exactly as it sends. Or ask AI to move a section or shorten the intro, and it keeps your copy, layout and links.

Questions, answered.

Everything you need to know before you start.

An AI-native email marketing tool for SaaS. Campaigns, automations and transactional email run from one account. It writes every email in your brand, sends on your product and billing events and reports revenue per email.

You pay for the emails you send each month, never for contacts. Contacts, lists, segments and sending domains are unlimited, and every plan has every feature. Free covers 2,500 emails a month with a small Sequenzy footer. Paid plans start at $19 and remove it.

Sequenzy reads your logo, colors, product and tone of voice, then drafts the emails you asked for. You can edit every email before anything goes out.

No. Drafts stay drafts until you schedule a campaign or turn a flow on. An AI agent connected over MCP can draft and set things up, and only sends to real contacts once you give it full access.

You send from your own domain, authenticated with SPF, DKIM and DMARC. Sequenzy checks addresses before sending, handles bounces and complaints, and pauses a campaign if bounces spike. Dedicated IPs are a $30 per IP per month add-on.

Stripe trial, payment, upgrade, downgrade and cancellation events, events from your app through the API, PostHog or Segment, joining a list, entering or leaving a segment, and inactivity. Paddle, Polar and other billing integrations sync too.

Payments from your billing provider are credited to the most recent email the customer opened or clicked, inside a window you choose. Goals track conversions that aren't payments, like connecting an integration.
