RealSender (plainmail app)

Squeeze your emails into a single line, convert email attachments into links

RealSender is an email delivery service built around dedicated SMTP infrastructure, with the plainmail app available to reduce message content to a single line of text. Adding ".plain" to a recipient's domain delivers only the subject line, while additional content and attachments are replaced with a notice. Writing "[A]" in the subject converts an attachment into a link hosted on a domain of your choice, with files deleted after six months.

The plainmail app is offered alongside RealSender's SMTP services. RealSender provides a single dedicated SMTP server for one-to-one and transactional email, while HighSender relays across multiple dedicated SMTP servers with automatic balancing for newsletters and mass mailings. Services identified as apps carry an additional cost. A free trial is available.
