BulkGate review: SMS, Viber, WhatsApp and RCS messaging with a portal and APIs. Pay-as-you-go from €0.002 per message, no monthly fees for SMS.
Researched and fact-checked by Bartu Cavusoglu · Updated October 26, 2026
BulkGate is a business messaging platform that lets companies send SMS, Viber, WhatsApp, RCS and voice messages from one account. Its site frames the problem simply: important messages such as verification codes, order updates and renewal alerts get lost in email inboxes and social feeds. The homepage says more than 15,000 businesses use it across 200 countries.
The platform is sold under the BulkGate brand, a registered trademark of TOPefekt s.r.o. It combines a web portal for sending without coding, APIs for developers, ready-made integrations and a white label option. The website is available in 17 languages, including English, German, Czech, Polish and Spanish.
Users register on the BulkGate portal with an email, password and phone number, which is verified with a six-digit code. After confirming the email address, they top up credit and start sending. The portal's campaign editor guides users from importing contacts to writing a message, scheduling it and sending, then shows campaign metrics.
Developers can connect through the APIs instead, or through integrations with e-commerce platforms and automation tools. Text sender IDs are registered by contacting BulkGate and choosing the country. Credit can be split across wallets, and messages can be routed through channel cascades that move to another channel based on delivery priority.
The channel coverage is the main draw. Bulk SMS, SMS notifications, SMS OTP, two-way SMS and Smart SMS with images, buttons and links sit alongside Viber Business, WhatsApp Business, RCS Business and Text to Voice. One Business Messaging API spans all channels, and separate APIs cover SMS, OTP, notifications and two-way replies via webhooks.
Several tools sit around the core. Mobile Connect turns an Android phone into an SMS gateway, BulkGate AI offers assistance for messages and campaigns, and the White Label platform puts the portal under a customer's own brand. The site also describes API limits designed to protect against hacked OTP SMS abuse.
