Sendblue
SendBlue is a messaging platform that lets businesses send iMessage, SMS, and MMS using virtual iMessage lines, with or without writing code. It avoids the need for A2P registration and supports rich media like voice memos, videos, and high-resolution photos. It’s particularly designed for sales and marketing workflows; messages automatically fall back to SMS on non-Apple devices, you can port your existing phone number into the system, and it integrates with your CRM so you can message prospects directly. SendBlue claims users see a ~70% increase in response rate by using iMessage instead of traditional texting channels. The platform also supports sending media types (voice, image, video), maintains “blue bubble” design to mimic native iMessage, and limits brute-force messaging by capping daily messages per phone line. We allow our users to send unlimited texts to their contacts.
