DualBlaster officially launches May 1, 2026
Send SMS and email campaigns using your own Twilio, SendGrid, or AWS keys — at a fraction of the cost.
Most marketing platforms resell SMS and email at inflated prices — and they control your sending reputation. DualBlaster is different.
Instead of reselling messages, we let you connect your own sending accounts (Twilio, AWS SES, SendGrid). We call this Bring Your Own Keys (BYOK) — and we walk you through every step.
Don't have sending accounts yet? No problem — we guide you step-by-step during setup.
Sign up with Twilio, AWS SES, SendGrid, or your preferred provider
Required for SMS/email compliance — we walk you through it

Use our AI tools, automations, and inbox — while paying wholesale rates
Most platforms mark up every message you send. With BYOK, you pay provider wholesale rates directly.
Most platforms cap how many messages you can send per month, then charge overage fees. DualBlaster has zero sending limits — send as much as your provider allows. You only pay your provider's per-message rate.
Your Twilio, SendGrid, and AWS credentials are encrypted with AES-256-GCM — the same encryption standard used by banks and government agencies. We never store or see your keys in plain text.
Reach your audience wherever they are
