SubAlert's homepage still offers a 21-day free trial, but its sign-up page is closed. What Frontline subs can use instead

If you clicked SubAlert's free trial and reached a page that would not let you sign up, the trial is not open to you. When we checked on September 28, 2026, subalert.com still listed two monthly plans and a "21-Day Free Trial, No Credit Card Required." The Sign Up button on that same page goes to a page with no sign-up form. It has only a notice that SubAlert is not accepting new customers. So a new substitute can see the offer but cannot take it. Three things are taking sign-ups for Frontline Absence Management today: the free Frontline Education app, Frontline's automated phone calls, and an independent alert service. This post covers what each of SubAlert's pages says, what that means if you already use it, and what each option does and leaves out.

What SubAlert's pages say, as of September 28, 2026

We opened each page on September 28, 2026. This is what they showed.

• The homepage, subalert.com. Two plans: "$4.95/month For App Alerts, Desktop Alerts, & Email Alerts" and "$6.95/month For Phone Call, Text, App, Desktop, & Email Alerts." Below them, "21-Day Free Trial, No Credit Card Required." There is no notice about new customers anywhere on the homepage.
• The Sign Up button. It links to subalert.com/sign_up. That page has a Sign Up heading and no form under it, only the notice that SubAlert is not accepting new customers.
• The Sign Up / Log In link. It goes to subalert.com/login, which shows the same notice beside a log-in form with email and password fields.

So the homepage and the sign-up page disagree. The homepage describes a trial you can start without a card. The sign-up page says you cannot become a customer. We covered the sign-up notice when it first appeared in our post on SubAlert not taking new customers. What has changed since is that people are still reaching the homepage offer first and finding out afterward.

Is SubAlert shutting down?

SubAlert's public pages don't put a date on it, and we only report what those pages say. They say it is not accepting new customers, and the log-in form is still there for current members. SubSidekick was different: its site said in August that the service had shut down. Our SubSidekick post covers that one.

If you already pay SubAlert, you may have heard more from SubAlert directly than its public site says. If it has written to you about your account, go by that message, not by us. For anything it has not covered, SubAlert's site has a Contact Us page, and SubAlert is the one to ask about your account, your billing or what comes next. We don't print a date that SubAlert's own pages don't state, and we don't use forum posts or app reviews to fill the gap.

Why the homepage still shows a trial

SubAlert's pages don't say, and we won't guess. The sign-up page is the one that decides whether you can join.

What matters for you is simpler. The price and the trial on that homepage are not something a new substitute can sign up for today. If you were planning around a 21-day trial, plan around the options below instead.

What you can sign up for instead

Option 1: the Frontline Education app. This is Frontline's own app, and it is free. There is no separate sign-up. You sign in with the Frontline login you already use and see the jobs available to you. It can send notifications about available jobs. Whether it tells you about a new job the moment it posts is a narrower question, and our post on the free app's notifications goes through what Frontline's pages say and what they leave out. If you have not set it up, start here. It costs nothing and it is already connected to your account.

Option 2: Frontline's automated phone calls. Frontline also places automated calls to substitutes about some open jobs. Our earlier SubAlert post covers when Frontline's help pages say those calls start. If you don't carry a smartphone, or you want a call on a phone without a data plan, this is the option closest to the phone and text alerts SubAlert listed.

Option 3: an independent alert service. These connect to your Frontline account and send you an alert when a job that matches your settings appears. Of the ones we have written about, Sub Hero is the one taking sign-ups. It is ours, so read this part as the interested party's description.

• Alerts come by email and push notification, within seconds of a job matching your filters.
• Filters cover school, district, position, day, time and length, so you hear about the jobs you would take and not the rest.
• On Pro, auto-accept can accept a matching job for you, with 5 auto-accepts included a month.
• A free account needs no card. Standard is $6.99 a month. Pro is $9.99 a month. There is a 14-day trial on Pro only, one per Frontline login. Our post on what is free lays out what each plan includes.

What SubAlert listed that Sub Hero does not do

SubAlert's homepage lists alerts by phone call, text, app, desktop and email. Sub Hero sends email and push. It does not call you and it does not send text messages. If a phone call is the alert you need, Frontline's own automated calls fit better than we do.

SubAlert's homepage also says you can book jobs from your phone without a smartphone or data plan. Sub Hero runs in a web browser and needs one to set filters and see alerts. If you have no smartphone and no computer handy during the day, Frontline's phone calls are the better fit.

Before you move to any service

This applies to us as much as anyone else.

• Open the sign-up page first. A price or a trial on a homepage is not a sign-up. The sign-up page tells you whether you can join.
• Check that it works with Frontline Absence Management. That is where your jobs are posted, so a service built for another system will not help.
• Check how alerts reach you. Email, push, text and phone calls are different things. Make sure the one you need is on the list.
• Ask how it stores your Frontline login, what it can do inside your account, and whether you can delete everything yourself. Our post on whether an alert service is safe lists the questions and what good answers look like.
• Leave any auto-accept feature off at first. Watch the alerts for a week and turn it on once the filters match what you would book.

What we can't tell you

• Why SubAlert's homepage still shows plans and a trial. Its pages don't say, and only SubAlert can.
• What happens to current members' accounts, or when. SubAlert's public pages don't give a date, so this post doesn't either. Members should go by what SubAlert tells them directly.
• How SubAlert is working for existing customers. We are not customers, and the log-in form being there does not tell us what happens after you sign in.
• Whether any of this is still true next week. These are the pages as they stood on September 28, 2026. Homepages and sign-up pages change.

Where Sub Hero fits

Sub Hero is an independent service for substitutes on Frontline Absence Management. It sends an email and push alert within seconds of a job matching your filters, and on Pro it can accept that job for you. It does not send texts or place calls. It cannot see the non-work days you set in Frontline, so a filter has to cover days you are unavailable. It cannot win a job that another substitute booked first. It does nothing outside Frontline.
