What it does
Monitors ActiveCampaign email engagement and sends a personalised SMS if the contact doesn’t open within 48 hours, driving replies through another channel.
Why I recommend it
Multi-channel follow-up dramatically improves response rates, especially for time-sensitive offers or appointments.
Expected benefits
- More replies from warm leads
- Higher show-up rates for booked calls
- Automated safety net without rep effort
- Better attribution of email campaigns
How it works
Automation waits 48 hours after sending email -> check open status -> if unopened and SMS consent true -> send text referencing the email value -> log outcome in CRM.
Quick start
Test with a single nurture email: segment contacts who didn’t open and manually text them. Measure reply lift before scaling.
Level-up version
A/B test copy, adjust timing based on lead score, throttle volume to respect carrier limits, and include opt-out confirmation.
Tools you can use
Marketing: ActiveCampaign
SMS: ActiveCampaign native SMS, Twilio, Sakari
Automation: ActiveCampaign automations, Zapier
CRM: HubSpot, Pipedrive
Also works with
Post-webinar reminders, event confirmations, onboarding check-ins.
Technical implementation solution
- No-code: ActiveCampaign automation branch -> if not opened -> send SMS step -> tag contact as “SMS follow-up”.
- API-based: Webhook to serverless function -> check engagement via API -> Twilio send -> log to CRM.
Where it gets tricky
Staying compliant with SMS regulations, respecting time zones, and ensuring you have consent before sending.
