Do parents have to be connected before the school can send them a Blast?
Yes. Blasts is connection-based, and DirectToParents is designed around the fact that a school already has an enrollment relationship with every family and a natural moment, back-to-school, when it can invite them.
Connections can be established through an email invite link, a 4-digit connection code printed on enrollment materials, or a personal invite link. Schools with an opted-in family roster can send personalized invitations at scale; see the implementation section above.
How does a school establish Blasts connections with families?
By offering the connection at enrollment and back-to-school: the school's invite link and 4-digit connection code go into the enrollment packet, registration confirmation, back-to-school night handout and welcome email, and an opted-in family roster can be invited with personalized invitations sent through the school's Google Workspace, Microsoft 365 or Amazon SES account. Parents accept once and then receive Blasts through the iOS or Android app, a browser extension, or the web app.
Parents always retain the ability to silently cut off the school. Step-by-step administrator instructions will be published in the DirectToParents school rollout guide once confirmed against current Blasts documentation.
Can we Blast every family in the district, or a list we bought?
No. A parent must approve the school's sender before any Blast is delivered. Blasts is built for existing relationships, which for DirectToParents means the families enrolled in your school or program.
How are Blasts different from robocalls or SMS for school alerts?
Blasts have no per-message carrier fee, travel over encrypted tunnels rather than the phone network, show the principal's or school's name and photo, and report read acknowledgements from confirmed actions. They require a prior connection, which a robocall list does not.
Can we send a closure notice to just one school, one grade, or the after-school program?
Yes. Distribution lists let a sender name a group once, such as a grade, a building, a bus route or a program, and reach every member at the same time with no per-recipient cap. Large lists can also be staggered into daily waves for non-urgent messages.
What does it cost to send a Blast to 600 families?
A typed Blast consumes one credit per recipient, so 600 credits; a voice Blast consumes two per recipient. Credits are prepaid, never expire, and are available through BlastCredits.com.
Is Blasts appropriate for a school from a privacy standpoint?
Blasts.app publishes the following: peer-to-peer encrypted tunnels using ECDH P-256 and AES-256-GCM, no tracking pixels, messages auto-deleted after 30 days with an optional self-destruct timer, and voice recordings not stored on central servers. Your district's technology and legal staff should evaluate these against your own policies; DirectToParents makes no regulatory compliance claims.
Which devices can parents receive Blasts on?
An iOS app, an Android app, browser extensions for Chrome, Edge, Brave, Opera, Vivaldi, Arc and other Chromium browsers, and the responsive web app at blasts.app.
