Everything you need to run professional email marketing campaigns from your own server

A drag-and-drop visual editor with live preview, mobile/desktop toggles, and undo history; 100+ ready-made templates spanning newsletters, e-commerce, onboarding, and transactional; HTML and plaintext modes with auto-generated plaintext fallback; inline image upload; subject-line and full-body A/B testing with auto-winner selection.

Workflows fire on triggers (signup, tag added, custom event, date relative, link clicked, field value change, workflow goal). Actions include send email, wait for a duration or condition, add or remove tags, move between lists, update fields, call a webhook, or end the workflow. Multi-branch conditional logic supports up to 16 paths per node.

Custom fields of any type (text, number, date, dropdown), tags with bulk apply or remove, segmentation by AND / OR / NOT logic across fields, tags, and behaviour history (opens, clicks, automation state). Lists support CSV and XLS import or export plus REST API sync.

Amazon SES (recommended for volume at USD 0.10 per 1,000 emails), SendGrid, Mailgun, SparkPost, Postmark, Elastic Email, Mailjet, MailerSend, Sendinblue / Brevo, plus any RFC-compliant SMTP server (Postfix, Exim, Sendmail, Qmail). Multiple servers can be configured simultaneously with round-robin or priority routing.

A SPF / DKIM / DMARC setup wizard with copy-paste DNS records, automatic bounce handling (hard bounces removed, soft bounces retried with backoff), List-Unsubscribe header per RFC 8058 + RFC 2369 so Gmail and Apple Mail render native unsubscribe buttons, feedback-loop integration for major ISPs, a warm-up scheduler for new IPs, and real-time bounce + complaint webhooks from supported SMTP vendors.

Regular License at USD 80 covers a single domain for internal or end-client use but cannot charge end users for access. Extended License at USD 199 adds SaaS rights: multi-tenant user management, per-plan quotas, Stripe / PayPal / Braintree billing modules, a reseller dashboard with MRR reporting, and white-label of every screen, email, and invoice.

Yes. REST API v1 and v2 cover lists, subscribers, campaigns, automations, and reports. Webhook events fire on subscribe, unsubscribe, open, click, bounce, complaint, and campaign status. A plugin system with hooks at every major UI surface lets you extend the application without forking core — the same pattern shipping plugins like Acelle AI and Acelle Messenger use.

Open and click maps with geographic data, funnel reports for automation goals, comparison reports across campaigns or time windows, subscriber engagement scoring, and per-subscriber activity timelines (opens, clicks, automations, list changes). Every report exports to CSV.
