With each passing month, our client base is growing. At some point, we started looking for new ways to send notifications and newsletters, both promotional and service-related. We focused mainly on automation, optimization, and speed. With the help of Stream Telecom, we are launching effective mailings. The company has a strong technical department and great capabilities for customizing the platform to our needs. We set up the integration and now send messages from Bitrix CRM. The option for automatic cascades is very convenient. I recommend the Stream Telecom team.
