Built for professionals who demand control

SendForge solves real problems for teams that need full ownership of their email sending infrastructure.

Own MTA Infrastructure

Campaign management without infrastructure migration. Connect your Postfix, Exim or cPanel server — and you're live.

High Volume Senders

Rate limiting, adaptive throttling, IP reputation monitoring, and intelligent routing across multiple sending nodes.

Features

Everything you need. Nothing you don't.

A complete toolkit for contacts, campaigns, and automations — with full control over your sending infrastructure.

Contacts

CSV import with deduplication, custom fields, tags, statuses, double opt-in, GDPR consent registry and global suppression list.

Segmentation

Dynamic segments recalculated before each send. AND/OR conditions on fields, tags, email activity and custom fields.

Campaigns

Step-by-step creator, drag & drop builder, personalization, scheduled sending, pause/resume and real-time statistics.

Automations

Visual workflow engine with triggers, if/else conditions, delays and ready-made welcome & nurturing templates.

Sending Nodes

Connect your SES, Mailgun, SendGrid or SMTP. Adaptive throttling, health dashboard, retry logic and node grouping.
