SendGrid Email Sequence + WhatsApp Amplifier Agent

AI listens to SendGrid email events (delivered, opened, clicked, bounced). For contacts who receive an email but don't open within 24 hours, AI sends a WhatsApp with the key message. This omnichannel amplification recovers 30–40% of email-only non-responders.

How It Works

01
SendGrid Event Monitoring
AI listens to SendGrid webhook events: delivered, opened, clicked, unsubscribed, bounced.
02
Non-Opener Detection
24 hours after email delivered, AI checks if contact opened. Non-openers added to WhatsApp follow-up queue.
03
WhatsApp Amplification
AI sends a concise WhatsApp with the key CTA from the email. Different tone - more direct, conversational.
04
Response Handling
WhatsApp reply captured and classified. Positive responses route to sales. Unsubscribe requests remove from all sequences.
05
Conversion Attribution
Conversions from WhatsApp follow-up tagged separately in CRM for channel attribution analysis.

Frequently Asked Questions

Does this require SendGrid Pro or Essentials?

Requires SendGrid Essentials or above with Event Webhook enabled.

Will contacts find WhatsApp follow-ups to email intrusive?

Opt-in and frequency controls prevent over-messaging. Best practice: maximum 1 WhatsApp per email send.

Can it handle bounces and unsubscribes from WhatsApp?

Yes. WhatsApp opt-outs are honoured immediately and sync back to SendGrid suppression list.

What improvement in email sequence conversion is typical?

Adding WhatsApp follow-up to non-openers improves overall sequence conversion by 30–40%.

Can it work with drip sequences of any length?

Yes. AI amplifies each individual email in the sequence, not just the first.
