NJ.com (serving a number of New Jersey papers, including The Star-Ledger, The Express-Times and other daily and weekly papers) has launched a Subtext campaign sending text updates on school reopenings in New Jersey.

The N.J. Schools News campaign signed up 1K+ subscribers within the first 24 hours of its launch last week, says Subtext.

The text alerts are free, and nj.com says it will only send texts when it matters. Advance Local ownsNJ.com.

Subtext is part of The Alpha Group, the in-house tech and media incubator for Advance Local.
