Overview
THE EMAIL NEWSLETTER PLATFORM THAT PUTS YOU IN CONTROL
The only serverless newsletter SaaS where every tenant sends from their own AWS SES. Unlike Mailchimp, ConvertKit, or Substack where one bad sender tanks everyone's deliverability, your sending reputation is 100% yours. No shared IPs. No noisy neighbors.
WHY TEAMS SWITCH FROM MAILCHIMP/CONVERTKIT:
- Shared infrastructure means YOUR emails land in spam because of OTHER senders
- No control over IP reputation or complaint rates
- Vendor lock-in with proprietary formats
- No AWS billing consolidation or enterprise procurement
BRING YOUR OWN SES (BYO SES) - TOTAL ISOLATION: Each customer sends from their own AWS SES account. Your domain, your reputation, your deliverability - completely isolated. You control bounce rates, complaint rates, and IP warming. SES costs on YOUR AWS bill ($0.10/1000 emails).
SHIELDFORM - INVISIBLE 3-LAYER BOT PROTECTION: Military-grade bot detection your visitors never see. No CAPTCHAs. No friction. Just clean lists.
- Layer 1: Honeypot + timestamp (catches 80% of bots instantly, zero cost)
- Layer 2: Behavioral AI (mouse movement, keystrokes, scroll, timing, fingerprint)
- Layer 3: SES email validation pre-flight (DNS + mailbox check before sending)
- Score 0-100: below 40 blocked, 40-69 challenged, 70+ allowed
- Real-time dashboard with score distribution, blocked IPs, repeat offenders
- Protects your SES reputation by preventing fake signups from triggering bounces
COMPLETE TOOLKIT:
- A/B subject line testing with automatic winner selection
- Real-time analytics: opens, clicks, engagement scores, growth
- Engagement: polls, likes, comments, social shares
- AI text-to-speech via Amazon Polly - newsletters become podcasts (Pro)
- Subscriber segmentation with tags and behavioral filters
- Import/export (CSV, no lock-in)
- Drip/welcome sequences with conditional logic
- Referral program with tiered rewards
- SEO-optimized archive pages
- Custom subdomain (newsletter.yourdomain.com)
- Double opt-in, one-click unsubscribe (CAN-SPAM/GDPR)
