Text your buyers with SMS campaigns

A flash sale ends tonight and half your buyers never open the email. A text gets read in minutes, but sending one meant another tool, another list and no idea which sale it brought in.
The enemy is a text you send blind.
SMS Campaigns is open to every brand, for numbers in the US. Connect Twilio, Plivo or Telnyx, add a sender and accept the marketing statement under Compliance. Then write a campaign in five steps: Setup, Audience, Message, Schedule and Review. The audience comes from your saved segments. People who opted out, have no phone number or are on the suppression list are skipped, and a number that appears twice gets one text. An opt-out line, Reply STOP to opt out by default, is added to every text unless you turn it off.
Every link becomes a tracked short link. Add up to five variants and the wording with the most clicks goes to everyone else. You can spread the sends over a few hours and keep texts inside the hours you choose, in each person's time zone. The report has a Revenue tab: sales from people who clicked, and sales in the 24 hours after the send from people who did not.
Try it: open Campaigns, then Senders under SMS to add a number. Then click New campaign and pick SMS broadcast.
