MailBluster supports the UTF8MB3 character set, which is a subset of UTF8MB4 (UTF-8). UTF8MB3 stands for “UTF-8 with a maximum of 3-byte characters.” It covers a broad range of characters used in different scripts. While UTF8MB4 supports up to 4-byte characters, UTF8MB3 provides a slightly smaller but still powerful range. By using UTF8MB3, MailBluster ensures smooth compatibility with diverse characters and symbols. This support helps users create compelling content and communicate effectively with a global audience.
