Blasts for youth and adult sports leagues
Connect families when they register and keep players, parents and coaches informed throughout the season: rainouts, field changes, schedule updates, volunteer needs and tournament weekends.
Built on Blasts. Connection-based, encrypted, no subscription, credits never expire.
League communication does not fail in the office. It fails in a parking lot at 8:15 a.m., with cleats on and no game to play.
The fields are underwater and the decision is made at 6:30 a.m. The email goes out to the whole league. By 8:15 there are eleven families at Field 4, the coach's group text has three parents who changed numbers, and the commissioner's phone is the league's real notification system.
The city pulled the permit for Field 2 and the U10 games are now across town. The change was posted on the website and sent in a league-wide email that most parents skimmed past, because it looked exactly like every other league email.
Brackets change hourly, the concession stand needs two more people at noon, and the referee assignor needs a lineup change confirmed. The information exists. It is scattered across a spreadsheet, a group text per team, and a coach who is on the field and cannot check his phone.
There's another way
Blasts is built around persistent connections between parties who already know each other. A family connects with the league once, at registration. From that point on, the league has a direct, encrypted channel that shows the message on the parent's, player's or coach's screen with the sender's name and photo, and an emergency badge that pulses red and pins to the top when a field closes.
Leagues have a moment every organization envies: registration, when every family fills out a form, pays a fee and expects to hear from you. That is where the connection happens.
A family registers a player, pays the fee and picks up the uniform. Right there, in the confirmation and at the pickup table, the league offers a direct connection.
The parent, player or coach accepts the league's connection on their phone. One connection, made once, and it carries from season to season.
From then on, the rainout, the field change, the makeup game and the concession-shift ask land directly on the sideline phone, sent to the right team or division, from a name they know.
Families opt in; a family that has not accepted the league's connection cannot be Blasted, and a parent or player can silently disconnect at any time.
The season newsletter still belongs in email. These messages belong on the screen.
Rainouts, lightning delays, heat holds, frozen fields. One Blast to the affected division, sent with the Emergency badge so it pins to the top and pulses red on every phone headed to the park.
A pulled permit, a flooded diamond, a gym double-booked. Sent to just the teams playing there, with a map image and a link, and read acknowledgements so the commissioner knows which families still need a call.
Rescheduled matchups, time changes, playoff seeding. Sent per team or division so the U8 makeup game does not interrupt the adult softball list.
Concession shifts, field prep, scorekeepers, team parents. A quick poll to the team list fills the slot without a reply-all thread.
Bracket updates, check-in instructions, parking, weather holds and the championship time, sent to the teams still playing. Event Blasts carry a countdown and a calendar attachment.
Registration deadlines, uniform pickup, picture day, opening day ceremonies, end-of-season party. Short typed Blasts to the right list, or a voice Blast from the commissioner families can play from the sideline.
Email is where the handbook and the schedule PDF live. Group texts are where wrong numbers, muted threads and reply-all live. A team app is only as good as the last coach who updated it. None of them was designed for a league that already knows every registered family by name.
Blasts credits are bought once and never expire. One typed Blast to one parent is one prepaid credit; a voice Blast is two. There is no carrier fee, so a league can budget a season, or a year of seasons, as a single deposit instead of a monthly platform fee that keeps billing in the off-season.
The message appears on the sideline phone with the league's name and photo. Read acknowledgements tell the commissioner who has actually seen the rainout, so the phone tree only has to cover the families who haven't.
Distribution lists per team, division, coach group and volunteer pool mean the U10 field change reaches U10 families and nobody else. Large lists can be staggered into daily waves for non-urgent, league-wide content.
Every Blast shows the sender's name and photo and a campaign badge (Emergency, Event, FYI, General and more). Families can revoke the league at any time without the league being notified. Messages auto-delete after 30 days with an optional self-destruct timer, and there are no tracking pixels.

Blasts is not a way to message strangers, and LeagueBlasts does not pretend otherwise. It is built for the audience a league knows completely: the players, parents and coaches on its rosters. That constraint is what makes the channel trustworthy for a parent who already juggles three teams and a dozen group texts.
For the person who will set it up
For the registrar, commissioner or board member who will set this up: here is what sits behind the three steps above.
Blasts gives the league a personal invite link and a 4-digit connection code. Add them to the registration confirmation page, the payment receipt email, the uniform-pickup handout and the coaches' preseason packet. Parents on their phone tap the link; parents at the pickup table enter the code. The league approves each request.
For a roster of players and families who have opted in to league communications, export it from your registration platform, upload it, and send personalized Blasts invitations at scale through your own email service (Amazon SES, Microsoft 365 or Gmail). Each family still approves the connection.
For nearly everyone that is the iOS or Android app. The registrar and board members at a desk can add the browser extension (Chrome, Edge, Brave and other Chromium browsers) or use the web app at blasts.app. Each device is a separate connection.
Create lists for the whole league, each division, each team, coaches, referees and volunteers. A list reaches every member at once with no per-recipient cap, and large league-wide lists can be staggered into daily waves for non-urgent content.
Typed Blasts with a field map, a voice Blast from the commissioner (auto-transcribed), Event Blasts with a countdown and calendar attachment for opening day and picture day, or a poll to fill the concession shift. Rainouts and field closures go out with the Emergency badge, which pulses red and auto-pins to the top.
Recruiting connections is a registration-season task, repeated each season for new families. Domain Auto-Approve is built for organizations whose members share a verified email domain, so it does not apply to league families. Exact administrator steps will be documented in the league season guide once confirmed against current Blasts documentation.
In one paragraph
LeagueBlasts is an implementation of Blasts for youth and adult sports leagues that need a direct communication channel with players, parents and coaches. Player and family registration is the moment a family connects once; from then on, weather cancellations, field changes, schedule updates, volunteer needs and tournament information land directly on the family's phone or desktop screen, sent to the right team or division instead of buried in a league-wide email or a group text someone muted.
Yes. Blasts is connection-based, and LeagueBlasts is designed around the fact that a league already has a registration relationship with every family and a natural moment, signup, when it can invite them.
Connections can be established through an email invite link, a 4-digit connection code on the registration confirmation or uniform-pickup handout, or a personal invite link. Leagues with an opted-in roster can send personalized invitations at scale; see the implementation section above.
By offering the connection at registration: the league's invite link and 4-digit connection code go into the registration confirmation, payment receipt, uniform-pickup handout and coaches' packet, and an opted-in registered roster can be invited with personalized invitations sent through the league's own email service. Families accept once and then receive Blasts through the iOS or Android app, a browser extension, or the web app.
Families always retain the ability to silently cut off the league. Step-by-step administrator instructions will be published in the LeagueBlasts season guide once confirmed against current Blasts documentation.
No. A family must approve the league's sender before any Blast is delivered. Blasts is built for existing relationships, which for LeagueBlasts means the players and families registered with your league who chose to connect.
Blasts have no per-message carrier fee, travel over encrypted tunnels rather than the carrier network, show the league's name and photo, and report read acknowledgements from confirmed actions. They are sent to named lists the league maintains, not to a text thread that breaks when a parent changes numbers, and they require a prior connection, which SMS does not.
Yes. Distribution lists let a sender name a group once, such as a team, a division, the coaches or the volunteer pool, and reach every member at the same time with no per-recipient cap. Large league-wide lists can be staggered into daily waves for non-urgent messages.
A typed Blast consumes one credit per recipient, so 400 credits; a voice Blast consumes two per recipient. Credits are prepaid, never expire, and are available through BlastCredits.com, so a spring-season deposit carries into fall.
Coaches and referees receive Blasts like any other connected recipient, so the league can keep a coaches list and a referees list alongside the team and division lists. Whether the league can delegate sending to individual coaches will be confirmed and documented in the season guide.
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.
