One Message, Every Channel, Guaranteed Delivery

Broadcast to email and SMS in one call. Or set a priority order where failed channels automatically fall back to the next.

Omnichannel messaging

Reach customers wherever they respond

Customers check email once a day but respond to SMS in minutes. Some prefer detailed emails while others act faster on text messages. Multisend sends to all channels simultaneously or cascades through them until the message lands.

Capabilities

Omnichannel delivery with automatic fallback

Simultaneous broadcast

Send the same message to email and SMS in a single API call. Each channel receives content formatted for its medium.

Priority-based fallback

Define a channel priority order. If the first channel fails or goes unread, the message automatically routes to the next channel in the sequence.

Conditional routing

Route messages based on delivery status. Email bounce triggers SMS fallback. No open after a defined period escalates to the next channel. Each condition maps to an automatic switch.

Channel-specific content

Define separate templates for each channel. Email gets the full HTML layout while SMS receives a condensed 160-character version of the same notification.

Cascade tracking

Track exactly which channel delivered each message. See the full cascade path: email attempted, bounced, SMS sent, delivered. One unified timeline per recipient.

Unified analytics

Compare channel performance in a single dashboard. Identify that SMS converts 3x better for appointment reminders while email works for weekly digests.

Why it matters

Guaranteed delivery across channels

Guarantee delivery for critical messages

Password resets, two-factor codes, and payment confirmations cannot afford delivery failures. A single channel approach means some messages never arrive. Priority cascading tries each channel until confirmation.
In practice

A password reset request sends email first. If the email bounces, SMS delivers within seconds. The customer resets their password regardless of which channel succeeds.

Match the channel to the message urgency

Marketing emails sit unread for days while time-sensitive alerts need immediate attention. Multisend routes each message type through channels that match its urgency without separate integration code.
In practice

Appointment reminders send 24 hours ahead via email. If no confirmation within 4 hours, SMS follows up. 30 minutes before the appointment, a final SMS reminder sends if still unconfirmed.

Reduce messaging costs with smart routing

SMS costs 10x more than email per message. Sending everything through SMS wastes budget on messages that would convert through cheaper channels. Priority routing uses expensive channels only when necessary.
In practice

Order confirmations start with email, which costs a fraction of SMS. Customers who have not opened email in 48 hours receive SMS as a fallback. Total messaging costs drop compared to SMS-only delivery.

Built for Your Workflow

Ship faster with solutions designed for real-world needs

How Conjoin solves this

Define a cascade of channels with automatic fallback. Multisend tries email first; if it bounces or fails, SMS sends within seconds. Delivery confirms through whichever channel succeeds.

Impact

Guarantee delivery of password resets and security alerts across unreliable channels.

How Conjoin solves this

Configure escalation rules based on time and engagement. Start with email 24 hours before an appointment; escalate to SMS 4 hours before if unopened; send a final SMS 30 minutes before if still unconfirmed.

Impact

Reduce missed appointments with timed escalation that matches urgency.

How Conjoin solves this

Route through email first and fall back to SMS only when email bounces or goes unopened for 48 hours. Reserve SMS budget for customers who need it.

Impact

Cut messaging costs significantly while maintaining delivery rates.

How Conjoin solves this

Send to all channels simultaneously with one API call. Email receives the full HTML template; SMS receives a condensed version. Both send in parallel.

Impact

Launch omnichannel campaigns without writing separate integration code per channel.
