The smartest way to reach every customer

Stop choosing between reach and engagement. BulkGate's multichannel messaging platform automatically selects the best channel for every message — maximum impact, minimum cost.

Start optimizing your messages

Even the best strategy has a trade-off

For messages that need to be noticed, business messaging is the obvious choice. But even this strategy hides a trade-off that can cost you money or customers.

A

SMS first

Universal reach

You can reach virtually every customer with a mobile phone.

Low engagement

Your messages are plain text. You lose branding, interactivity and the impact of rich channels.

B

Rich channel first

High engagement

You can send beautiful, interactive messages that drive action.

Limited reach

You risk missing every customer who doesn't have the app installed.

Reach and engage everyone with multichannel messaging

Our multichannel platform automatically chooses the best route for every message, combining maximum reach with higher engagement.

Step 1

You set the channel priority

Set the order for maximum engagement or the lowest cost. Tailor the sequence to each user's preferences.

Step 2

We attempt delivery

The system immediately sends your message via your highest-priority channel. If it can't be delivered (e.g. the user doesn't have the app), the attempt fails — at zero cost to you.

Step 3

We automatically try the next channel

The system immediately retries, this time using the next channel in your sequence. This process repeats until the message is successfully sent.

Step 4

The result

Your message ends up on the most effective channel for each individual user. You only pay for one successful delivery in the entire chain.

Frequently asked questions

How does billing work for a cascade message?

You are always billed only once per cascade, for the first message in your sequence that is successfully handed off to the channel's gateway.

Here's a clear example: Imagine a Viber → SMS cascade.

1. We attempt to send the message via Viber. The user doesn't have the app. This is a channel-level failure. This attempt is completely free.
2. The system automatically sends the message via SMS. This is a successful handoff to the SMS gateway. You are charged for this SMS message.

The charge applies at this handoff stage, regardless of the final delivery status from the carrier. The key benefit is that you never pay for unsuccessful attempts on previous channels in the cascade.

How do I set up a channel cascade?

It's simple. In our web portal, you can create a campaign and set up the fallback sequence in the UI. Via our API, just list the desired channels in a prioritized array.

How does the system choose a channel if a user has multiple apps?

You're always in control. The platform will follow the exact priority order you define in your cascade. For example, if you set Viber SMS and the user has both, we will always try Viber first.

Can routing consider user data?

Yes. Beyond the default campaign cascade, our API enables even smarter targeting. You can override the sequence for any individual based on their data, such as a known channel preference.

Is a multichannel strategy more expensive?

No, it's designed to be more cost-effective. By prioritizing low-cost rich channels and using SMS only as a fallback, the system actively works to reduce your overall spend.

Do I need a verified business profile for each channel?

Yes, most rich channels such as WhatsApp, Viber and RCS require a verified business profile or Sender ID. We'll guide you through the simple setup process for each channel you wish to use.

How does multichannel messaging improve delivery reliability?

If a message cannot be delivered through the first selected channel, BulkGate automatically continues with the next channel in the configured cascade. This increases the chance that the message actually reaches the recipient. Learn more about how we ensure reliable message delivery.

Can I use multichannel messaging for international communication?

Yes. The availability of individual channels may vary by country, so you can tailor their combination to your target market. Find more information about coverage and international delivery in our overview of global message delivery.
