What's inside

A complete platform for outbound email.

Everything you need to send, monitor, and troubleshoot email at scale — in one web interface and a simple SMTP endpoint.

Multi-org & servers

Organize sending by organization, mail server, and user. Isolate environments for staging, production, and per-client workloads.

DKIM signing

Every outbound message is signed with a domain-level DKIM key. SPF and DMARC records are generated for you at domain setup.

IP pool management

Create multiple sending IP pools and route senders, recipients, or tagged traffic through different pools to protect reputation.

Open & click tracking

See when recipients open messages and click links. Aggregate engagement by campaign, tag, or individual message.

Suppression list

Hard bounces, unsubscribes, and complaints are automatically suppressed — protecting your sender reputation without manual effort.

Message logs & search

Every message is logged with full headers and delivery events. Search across organizations, domains, tags, and recipients.

Webhooks

Subscribe to delivery, bounce, and engagement events via HTTP. Last seven days of webhook requests are retained for debugging.

Tagging

Tag messages by type — receipts, password resets, campaign name — and filter, suppress, or route by tag without changing code.

Held messages (dev mode)

Hold outbound mail in the platform during development. Inspect the exact rendered message without it ever leaving the server.

Built to operate

Watch every message. Debug every delivery.

A purpose-built admin interface lets your ops team investigate issues, manage credentials, and tune deliverability.

Server-wide search

Find any message by recipient, subject, tag, or date range across all your organizations and servers.

Live queue visibility

Inspect the full outbound and incoming message queue in real time — retries, deferrals, and delivery attempts included.

DNS health monitoring

Built-in DNS checks catch misconfigured SPF, DKIM, MX, or return-path records before deliverability is affected.

Rate & retention controls

Set per-server send limits, message retention windows, and maximum storage to keep costs and abuse under control.

Spam & virus scanning

Inbound and outbound messages are inspected with configurable thresholds and policies for handling risky content.

Use cases

One platform. Many types of email.

Send transactional, operational, and marketing email from the same infrastructure — with the routing and controls each needs.

Transactional

Receipts, resets & confirmations

Low-latency delivery of the critical one-to-one mail users expect to see in seconds.

  • Sub-second SMTP accept
  • Dedicated transactional pool
  • Webhook on delivery
Bulk

Newsletters & campaigns

Throughput for large sends with per-tag routing and warm-up-managed IP pools.

  • Dedicated marketing pool
  • Click + open tracking
  • Automatic suppressions
Operational

Alerts & internal mail

Noisy ops mail kept clean with tagging, per-server limits, and a separate sending identity.

  • Isolated org per environment
  • Dev-mode held messages
  • Retention per server

Reliable email, without the operational weight.

SureContact SMTP handles authentication, deliverability, and observability so your team can focus on building the product — not fighting the inbox.
