Connect every provider you already use.
Route by rules, segments, or cost.
One subscriber history your team, and your AI agents, can finally trust.
Every open, click, bounce, and reply, from every provider, written to one subscriber record. Your AI agents stop guessing and start triggering the right email at the right second.
Connection, routing, and one clean subscriber history. So your team ships outcomes, not glue.
Plug in every provider you already pay for. One API. One auth flow. One bill to reason about.
Change routing by domain, segment, type, or cost. Live, from the dashboard. No PRs. No 3am pages.
Every send, every provider, on the same timeline. Your AI agents (and your support team) finally see the same picture.
Real numbers from teams running on Senderstool today.
Open in SendGrid. Click in Mailgun. Reply via SES. Senderstool stitches it all to one record, in real time, with a clean event timeline your team and your AI agents can both query.
SES throttling you? Postmark on incident? We notice in seconds and reroute. Your inboxing rate doesn't blink, and your reputation stays warm on every provider you didn't fail over to.
Three signs Senderstool fits: you send a lot, you depend on it, and you'd rather not babysit 4 dashboards.
Send millions through raw engines like SES, without losing the dashboard your team needs.
Transactional, marketing, and product email in one place, instead of three vendors and four dashboards.
Subscriber records your team, and your AI personalization, can finally rely on.
Trial signups. Receipt opens. Onboarding replies. Re-engagement clicks. Stripe webhooks. All on the same subscriber record. So churn signals, lifecycle triggers, and weekly digests share the same source of truth.
Trial → activation → paid → churn → win-back. Stitched across every email type you send, so the funnel is one story, not three reports.
Transactional opens, newsletter clicks, and product webhooks land on a single profile your CRM, your dashboards, and your AI agents can read.
Fire the win-back when the receipt was opened but the product wasn't. Skip the digest when they replied to support yesterday.
Shopify, WooCommerce, BigCommerce, Magento. Klaviyo, Postmark, transactional, support. One customer, one story. Promo bursts that survive Black Friday without torching deliverability.
Shopify, Klaviyo, transactional, support. Collapsed onto one profile. Cart abandons don't fire on customers who already bought.
VIPs ride premium deliverability. Dormant lists run on a fenced pool so a re-engagement push can't poison your main reputation.
Promo bursts spread across providers automatically. When SES throttles at 2am Black Friday, the next million keeps moving.
Failover, suppression, warmup. All handled. Send millions a day without babysitting four dashboards.
Per-route, per-provider health checks every 10 seconds. When one stumbles, traffic rebalances before your on-call pings.
