Send broadcasts, drips, and transactional templates from your own domain, with SPF / DKIM / DMARC handled, deliverability tracked at the campaign + recipient level, behaviour-based segments built from your Growth event stream, and A/B subject-line testing with a clear winner declaration. Mailchimp-class workflows, Resend-grade deliverability.
From draft to deliverability
Add your sending domain. ThorStack walks you through SPF, DKIM, and DMARC DNS records; checks return green only when all three pass. Per-domain reputation surfaced.
Native signup forms (single-step + multi-step + progressive) feed directly into Subscription Lists. Embed on your site or use as the form layer behind a Growth popup.
Template editor with WYSIWYG, drag-drop blocks, and AI-assisted draft from a brief. Brand styles applied automatically. Per-recipient personalisation tokens with safe defaults.
Behaviour-based segments from the Growth event stream: "visited /pricing twice in last 7 days," "opened last 3 broadcasts," "high lead score, no demo." Same segment language across Growth and Email.
Broadcasts, drip sequences, or transactional triggers, all on the same engine. Per-campaign send-rate throttling. Sandbox preview to a test inbox before the real fan-out.
Per-campaign + per-recipient open / click / bounce / complaint tracking. Heatmapped link clicks. Cohort comparison across campaigns. Suppression-list auto-managed on hard bounce / unsubscribe / spam report.
Nine integrated capabilities
Capability 01
A campaign is a campaign. Whether it's a one-shot newsletter, a 5-step welcome drip, or a transactional receipt, the same template + send mechanics + tracking apply. Switch send-modes without rebuilding.
Capability 02
WYSIWYG with drag-drop blocks (heading, paragraph, image, button, divider, columns). AI-assisted first draft from a brief pulls brand voice from your Marketing Studio profile so every send sounds like you.
Capability 03
Native form builder for inline + popup signup. Custom fields, validation, double-opt-in, confirmation email auto-shipped. Embed via JS snippet OR reuse as the form layer behind a Growth popup.
Capability 04
Define cohorts from the Growth event stream: page visits, popup conversions, scroll depth, country, device, lead score. Live count preview as you build. Same segment language Growth uses; one mental model.
Capability 05
Two-or-more variants on subject line OR sender name. Send variants to a configurable hold-out fraction, then auto-promote the winner to the remaining list based on open-rate uplift with significance check.
Capability 06
Workflow engine for non-broadcast sends. "New CRM contact" → 3-step welcome drip. "Lead score crosses 70" → demo-invite email. "Pricing page visited 3x" → sales-touch alert + email.
Capability 07
Per-campaign + per-recipient open / click / bounce / complaint. Soft + hard bounce auto-suppression. Domain reputation dashboard surfaced from Resend's deliverability signals.
Capability 08
First-class list management. Import CSV, sync from CRM, capture via form. GDPR / NDPR / CASL / CAN-SPAM-compliant double opt-in flows out of the box. Unsubscribe link on every send with one-click compliance.
Capability 09
Sending happens on Resend's infrastructure for high deliverability and transactional-grade throughput. Sends FROM your domain (SPF/DKIM/DMARC verified), not a shared sender. Your reputation, your inbox placement.
