Connect Email, SMS, and WhatsApp Into One Marketing Engine

Multi-Channel Integration links your email, SMS, WhatsApp, and other messaging tools into a single system. Build one campaign that reaches customers on the channel that works for them, backed by one shared set of contact data instead of four disconnected tools and four separate logins.

Benefits

Every channel you connect feeds the same contact record and campaign engine, so activity on one channel can trigger a follow-up on another without anyone exporting a spreadsheet.

One Setup, Every Channel

Connect email, SMS, WhatsApp, and live chat once, instead of configuring and maintaining a separate account for each provider. New channels plug into the same setup as the ones you already have running.

Synced Contact Data

Every connected channel reads from the same contact record. A segment built from email activity is ready to use for an SMS or WhatsApp send without re-uploading a single list.

Coordinated Campaigns

Build one journey that spans channels instead of running three separate campaigns by hand. Start with email, then follow up by SMS or WhatsApp only for contacts who did not open or respond.

Cross-channel reporting preview

Cross-Channel Reporting

Compare open rates, click rates, and replies across email, SMS, and WhatsApp side by side, so you can see which channel actually drives conversions for a given audience.

Features

Here is what changes once your channels stop working in isolation.

Unified Contact Sync

Connect email, SMS, WhatsApp, and social channels to one contact database instead of four separate lists. Update a customer's details once and every channel sends to the current record, not a stale export.

Audience Segmentation

Segment your audience based on demographics, behavior, or past interactions, then reuse that same segment across email, SMS, and WhatsApp instead of rebuilding it per channel.

WhatsApp as a Campaign Channel

Add WhatsApp to your campaign mix alongside email and SMS. Send order updates or promotions on the channel your Nigerian customers already have open, using the same segments and templates as your other channels.
