Campaign Management

Create, schedule,
and send at scale.

4-Step Campaign Wizard
Define details, pick recipients, design in the visual editor, then review and schedule. Clear progress at every step.
Smart Scheduling
Set exact send times. The background engine polls every 60 seconds, respects SMTP rate limits, and auto-retries transient failures.
Duplicate Campaigns
Clone any sent or draft campaign. Reuse successful templates, adjust the content, and resend to a different segment.
Delivery Tracking
Track every send: delivered, bounced, failed. Hard bounces automatically suppress the contact. Soft bounces are retried.
Click Tracking
Every link in your email is wrapped with a tracking redirect. See which links get the most engagement per campaign.
Pause & Resume
Pause a campaign mid-send if something needs fixing. Resume exactly where it left off — no duplicate sends.
Analytics

Data that actually
drives decisions.

Campaign Analytics
Open rate, click rate, bounce rate, CTOR, unsubscribes, and spam complaints — all per campaign with trend lines.
Device Breakdown
See if your subscribers open on mobile or desktop. Optimize layouts for the devices your audience actually uses.
Email Client Report
Know if Gmail, Outlook, or Apple Mail dominates your audience. Design for reality, not guesswork.
30-Day Volume Chart
Dashboard shows daily email volume over the last 30 days. Spot sending patterns and delivery anomalies at a glance.
Subscriber Health
Active vs. unsubscribed vs. bounced vs. complained — track list hygiene over time to maintain deliverability.
CSV Export
Export any analytics view, contact list, or campaign send log to CSV. Your data, always accessible.
Inbound Email Parsing

Receive emails.
Trigger workflows.

Like SendGrid Inbound Parse — but built in. Every handler gets a unique email address. When someone emails it, MailForge parses it, creates a contact, applies tags, and fires a signed webhook to your CRM or automation tool.

  • Unique inbound address per handler
  • Auto-create contacts from incoming senders
  • Apply tags + add to contact lists on receipt
  • HMAC-SHA256 signed webhook payload
  • Full log: subject, body, sender, forward status
  • Works with any SMTP relay or MX routing rule
  • API to manage handlers: GET/POST /api/v1/inbound
Use Cases

Route support replies into your helpdesk automatically

Every email to your sales address creates a CRM lead

REST API + Webhooks

Integrate with
anything.

Every organization gets a unique API key. 28 endpoints covering contacts, lists, campaigns, inbound email, suppressions, webhooks, and account usage.

API Key Auth
Bearer token or X-API-Key header. Generate keys in Settings → API Keys. Revoke instantly if compromised.

Security & Teams

Enterprise security,
built in.

Email Verification
All new organizations verify their email before first login. Prevents spam registrations and secures your platform.
CSRF Protection
Every form and state-changing endpoint is CSRF-protected via Flask-WTF tokens. Prevents cross-site request forgery attacks.
HMAC-SHA256 Signing
Outbound webhooks, inbound forwards, and unsubscribe links are all HMAC-SHA256 signed. Verify every payload.
Role-Based Access
Admin, Editor, Viewer roles enforced on every route. Invite team members via email with 72-hour expiry tokens.
