Features
Transactional and marketing email. Separate rails, one platform.
SMTP relay, REST API, and a native MCP server for AI agents — plus AI-generated marketing campaigns on a dedicated delivery pool. 35+ ready-to-send templates, real-time event pipeline, per-email status. SPF, DKIM, suppression, bounce + complaint handling wired up out of the box.
AI agents
Run your email from any AI agent.
Native MCP server at ai.sesmetric.com/mcp. Claude, ChatGPT, Cursor, custom agents — send transactional mail, and manage the entire marketing surface: contacts, segments, templates, campaigns, analytics. No glue code.
MCP server, out of the box
37 tools spanning transactional send and the full campaign lifecycle — create, generate, test-send, schedule, pause, and measure campaigns from your agent. Same API key as the REST surface.
35+ templates, no clone required
Send any system template by slug. Branding (logo, colors, footer, legal links) auto-applied. Customize a clone only when you need to tweak copy.
Per-email status, queryable
Pass the returned id to get_email_status — see sent → delivered → opened → clicked / bounced / complained as a single timeline.
AI campaigns
Marketing email, written and run by AI.
Describe the campaign in a prompt — the AI writes the email or a multi-step drip sequence in your chosen voice. Sends go out over our proprietary dedicated pool, never SES, never near your transactional reputation.
Prompt to campaign
One-shot emails or drip sequences generated from a prompt, with persona voices (founder, friendly, professional, playful, urgent). Cookbook recipes and a template catalog when you'd rather start from a base.
Segments that know your readers
Contacts carry live open/click engagement from your email events. Build rule-based segments on attributes and behavior — target openers, re-engage the dormant.
Deliverability by isolation
Campaign traffic runs on its own IP pool with warmup rate controls, one-click unsubscribe on every message, and abuse detection. Your receipts never share rails with promotions.
Analytics
Every event, in real time.
Sends, opens, clicks, bounces, complaints — streamed to a dashboard you can actually read at 3am during an incident.
Real-time dashboard
Live counters for sends, opens, clicks, bounces, complaints. Updates the moment SES emits the event.
Reports + exports
Slice deliveries, bounces, complaints, opens, clicks by date, domain, recipient. CSV out, no quota.
Historical compare
Pick any two ranges, see deltas. Catch reputation drift before AWS sends the warning email.
Deliverability
Inbox placement is the only number that matters.
Authentication, suppression, and bounce handling configured by default — no DNS spelunking required for email-only identities.
SPF + DKIM + DMARC
Auto-configured for single addresses. Guided setup for domains, with copyable CNAME / TXT records.
Domain verification
Verify a sending domain in one paste. We poll until the records propagate, no manual refresh.
Suppression list
Hard bounces and complaints land in the suppression list automatically. Add or remove manually any time.
Integration
Wire it in once.
SMTP and REST APIs that look like every other modern provider — slot it in with a single env-var change.
Open + click tracking
Pixel and link rewriting on by default for HTML mail. Off-switch per user, per domain, per send.
SMTP + REST API
SMTP on 2525 / 465 / 587. REST API mirrors SES SendRawEmail. Keys scoped per app, revocable any time.
Team access
Role-based access on the dashboard. Shared sending domains, separate API keys per teammate.
Get started
Send your first mail in under five minutes.
Sign up, verify a domain or single address, drop your SMTP creds into the framework you already use. Then hand the marketing to your AI agent at ai.sesmetric.com/mcp.
