Waltsoft Newsletter Platform

Waltsoft Newsletter Platform is a fully serverless, multi-tenant email newsletter platform built on AWS. Create and send beautiful newsletters with built-in subscriber management, double opt-in, A/B testing, engagement analytics, and AI-narrated audio via Amazon Polly.

BRING YOUR OWN SES (BYO SES): Each customer sends emails from their own AWS SES account. Your domain, your reputation, your deliverability - completely isolated from other tenants. No shared sending infrastructure.

Key features:

• Subscriber management with import/export and segmentation
• Template-based newsletter creation with live preview
• A/B subject line testing with automatic winner selection
• Real-time analytics dashboard (opens, clicks, engagement)
• Engagement features: polls, likes, comments, shares
• AI text-to-speech narration via Amazon Polly (Pro tier)
• Static archive pages with SEO optimization
• Referral program with tiered rewards
• Drip/welcome email sequences
• Custom subdomain support

PREREQUISITES (before using):

1. AWS SES account with production access (not sandbox) in your preferred region
2. Verified sending domain or email address in your SES
3. IAM role named newsletter-byo-ses-* (e.g., newsletter-byo-ses-production) with trust policy allowing arn:aws:iam::283023040015:root to assume it, ExternalId set to your tenant ID (provided after registration), and sesv2:SendEmail permission
4. DKIM/SPF/DMARC configured on your sending domain (recommended for deliverability)

SETUP (after subscribing):

1. Subscribe and complete registration
2. Create the IAM role in your account (CloudFormation template provided)
3. In the dashboard, go to Settings - SES Configuration
4. Enter your role ARN, SES region, and verified sender email
5. Click Verify - a test email confirms the connection
6. Start sending newsletters from your own domain

HOW IT WORKS:

• Platform runs in our account (serverless, managed)
• When you publish a newsletter, our Lambda assumes your IAM role
• Emails are sent via YOUR SES account, from YOUR domain
• Bounces and complaints stay in YOUR SES (your reputation, your control)
• You pay SES costs directly to AWS (typically $0.10 per 1000 emails)
• We charge for the platform only

IMPORTANT LIMITATIONS:

• Requires AWS SES production access (not sandbox). Sandbox limits sending to verified emails only.
• IAM role must follow naming convention: newsletter-byo-ses-* (security requirement)
• SES sending limits are YOUR account limits - we do not control or increase them
• Email deliverability depends on YOUR domain reputation and SES configuration
• Waltsoft is not responsible for deliverability issues caused by customer SES configuration

Pricing: Starter at $29/mo (5K emails). Growth at $79/mo (25K emails). Pro at $249/mo (100K emails + Polly TTS).
