WhatsApp & SMS Follow-Up
Follow up instantly. On the channel they prefer.
Send WhatsApp messages or SMS right after a call — with personalized templates, merge fields, delivery tracking, and full campaign integration. Omnichannel follow-up, built in.
Quick answer
What is WhatsApp and SMS follow-up in DialerBee? DialerBee integrates WhatsApp Business API and SMS messaging as post-call follow-up channels. After a call completes, the system can automatically send a personalized message based on the call disposition — for example, sending a pricing link after an "Interested" disposition or a callback confirmation after a "Callback" disposition. Features include template library with approval workflows for WhatsApp Business compliance, merge fields for dynamic personalization, disposition-triggered automated messaging, SMS fallback when WhatsApp is unavailable, delivery tracking (sent, delivered, read, replied), opt-out management with automatic STOP handling, and per-campaign channel selection. Available in 9 languages with multi-tenant isolation.
The Problem
Calls alone leave money on the table
Outbound teams that rely solely on voice calls miss a significant portion of their addressable audience. Not everyone answers the phone — and of those who do, many need a follow-up touchpoint to take the next step. A prospect who expressed interest on a call but did not convert needs a pricing link. A debtor who agreed to a payment plan needs written confirmation. A lead who missed the call needs a reason to call back.
Without built-in messaging, teams resort to manual follow-up workflows: agents copy phone numbers into a separate messaging tool, paste template text, and type personalization details by hand. This is slow, error-prone, and impossible to track at scale. Worse, it creates a gap between the call and the follow-up — a gap where momentum is lost and conversion drops.
The solution is not adding another messaging tool — it is integrating messaging directly into the dialer workflow. When the follow-up message fires automatically based on the call outcome, with the right template, the right personalization, and the right channel, the agent does not have to think about it. The follow-up happens every time, for every call, without manual intervention.
How It Works
Call, then message — in one workflow
DialerBee's omnichannel follow-up integrates WhatsApp Business API and SMS directly into the dialer workflow. After a call completes, the system can automatically send a follow-up message based on the disposition the agent selected. No separate tool, no manual sending, no copy-paste. The message fires with the right template, the right personalization, and delivery tracking built in.
Call Completes
Agent finishes the call and sets a disposition. The follow-up workflow triggers automatically based on the outcome — no manual messaging required.
Channel Selection
Send via WhatsApp Business API or SMS — based on contact preference, country, or campaign rules. SMS fallback when WhatsApp is unavailable.
Personalization
Templates with merge fields pull contact name, agent name, and custom data. Every message is personalized automatically. No manual editing.
Track Delivery
Track sent, delivered, read, and replied status for every message. Full visibility into follow-up performance across campaigns.
