What Iflow does

Iflow is a business SMS service. It sends text messages from your organisation to mobile phones, one at a time or thousands at once, and receives the replies. Iflow has been sending business SMS since 1998 and is run by DiaryBook Limited in Dublin.

Three ways to send

MethodBest for
Web portalSending by hand to a person, a group or an uploaded list
Email to SMSStaff who work from their inbox, and systems that already send email alerts
DiaryBook APIYour own applications, databases and monitoring tools

All three use the same account, the same credit and the same sender IDs.

Who your message comes from

Each message shows a sender. It can be:

  • A sender ID: your organisation’s name, up to 11 characters, such as YOURORG. People see at a glance who the message is from, but they can’t reply to it. In Ireland a sender ID must be registered with ComReg.
  • A reply number: a phone number that people can reply to. Replies arrive back in your Iflow account.

See Sender IDs for how to choose.

What it costs

You pay for each message part sent and each reply received, at the rates for your country, plus a monthly subscription that depends on your subscription level. Current prices are on the pricing page.
