Complete email infrastructure

Telesign Email Suite

Transactional, OTP, and promotional email on one API. A full campaign execution layer. Deployment on your infrastructure or ours. And when you’re ready to go deeper on deliverability, a report built from your own traffic—not a generic audit.

OTP

The complete email stacK

Four pillars. One platform. 

Email API

One engine for every traffic type, from real-time OTPs and alerts to high-volume promotional and lifecycle campaigns. Fully authenticated via REST API or SMTP relay.

Campaign Manager

Upload your list, define your segment, choose your template, send—full reporting included, no separate marketing platform needed.

MTA Deployment

Cloud, hybrid, or fully on-premises. The MTA is built in-house, so deployment topology is a real architectural choice.

Deliverability Consultation

A paid, on-request engagement. After your traffic runs on our infrastructure for a 60-day pilot, with no volume cap, you get a forensic report on exactly what's happening with your sending and a scoped conversation about fixing what it finds.

No leap of faith

How this actually starts

From first check to full clarity—the path most clients take

Step 1

Free deliverability check 

A pre-migration diagnostic on your current setup: authentication status (SPF/DKIM/DMARC), domain sending history, migration readiness, and any existing reputation signals visible in Google Postmaster Tools, Yahoo Postmaster, and Microsoft SNDS. No commitment, no full switch required.

Step 2

Full-volume switch 

60-day pilot, no volume cap. Move your real sending volume onto the platform with standard deliverability protection from day one—submission-time scrubbing, IP warm-up, suppression management. Unlike trial tiers that throttle volume, the pilot runs at your actual sending scale. 

Step 3

The 90-day forensic report 

After 60 days of full-volume sending on our infrastructure, you get a report built entirely from your own traffic on this platform—not your history elsewhere: bounce patterns, complaint trends, authentication performance, anything quietly costing you inbox placement. 

Step 4

Deliverability consultation 

A paid, scoped engagement built around the specific issues your own data surfaced — not a generic retainer. This happens only if the report shows something worth solving. 

Email API, in depth

Single-send path

Real-time transactional messages, priority-queued for sub-second dispatch. 

Bulk-send path

Promotional and lifecycle campaigns, throughput-optimized with per-destination rate shaping. 

Shared authentication, isolated reputation

One DKIM/SPF setup across both paths; IP pools isolated by traffic type. 

REST API

JSON, per-message and batch endpoints, idempotency-key support. 

SMTP relay

Genuine drop-in (587/STARTTLS, 465/implicit TLS), no code changes. 

Webhooks

HMAC-signed, real-time delivery/bounce/complaint/open/click events. 

Campaign Manager, in depth

Contact list to delivered campaign, in one flow

Ingestion

Upload contact lists directly; every import runs through the same list-hygiene checks as the API path. 

Segmentation

Filter by any attribute in your uploaded data. 

Templating

Build or select a template with merge-tag personalization. 

Delivery

Runs through the same bulk-send infrastructure as the API—same warm-up state, same reputation protection. 

Reporting

Opens, clicks, bounces (classified), complaints, per campaign. 

Deployment, in depth

Because the MTA is built in-house, deployment is a real configuration choice, not a pricing tier. Among API-first, campaign-capable email platforms, offering all three modes is effectively unmatched—mainstream cloud-only providers don’t offer on-premises deployment at all.

Cloud

Fully managed, fastest time to first send.

Hybrid

You host the receiving MTA, we handle outbound; data stays on your infrastructure with cloud-grade routing.

On-Premises

Both MTAs run inside your data center with fully controlled, audited network egress.

Deliverability Consultation, in depth

The free check looks at your history before you switch. The 90-day forensic report looks at your actual performance after you switch — on our infrastructure, not someone else’s.
