T-Alerts FAQ (Frequently Asked Questions)
What is T-Alerts?
T-Alerts is a service offered by the MBTA that lets you sign up to receive emails or text messages (SMS) notifying you about delays, disruptions, and service changes that affect the MBTA services you use most.
How do I subscribe to T-Alerts or manage my subscription?
Click here to sign up for the new T-Alerts service or manage your subcription.
Should I subscribe to receive emails or text messages?
We offer both, but we find that customers with email subscriptions are happier with the service. The email versions of the alerts sometimes have more detail or are more readable. Some customers subscribed to both tell us that the text messages are sometimes delayed; not all cellular service providers transmit our text messages to their customers right away.
How do I unsubscribe?
You can unsubscribe using the link above (after you log in click "subscriber preferences," scroll to the bottom and click "delete my account.") Or:
- If subscribed by email: click "one-click unsubscribe" at the bottom of the message.
- If subscribed by text message (SMS): text the word STOP to the number 468311.
If you are having difficulty unsubscribing contact GovDelivery support at firstname.lastname@example.org or call 1-800-439-1420.
Who is GovDelivery?
The MBTA has partnered with GovDelivery to send alerts to subscribers. You may see GovDelivery’s name associated with messages; this is normal.
What time periods should I sign up for?
It’s up to you. If you sign up for “Early AM,” you may receive alerts – even text messages – in the middle of the night.
What do the time periods mean?
Here are the exact times:
- Early AM: 2:30am-6:59am (Every day)
- AM Peak: 7:00am-8:59am (Weekdays)
- Midday: 9:00am-3:59pm (Weekdays)
- PM Peak: 4:00pm-6:29pm (Weekdays)
- Evening: 6:30pm-2:29am (Weekdays)
- Weekend: 7:00am-2:29am (Saturday, Sunday)
What do alerts like "minor delay," "moderate delay," "severe delay" mean? How will each delay affect my commute?
Minor: Schedules are slightly affected with passengers experiencing minimal service disruptions and trains/buses arriving at stations/stops with heavy passenger loads.
Moderate: Schedules are considerably affected as service is experiencing a major disruption in service. Passengers may experience trains/buses arriving at stations/stops with heavy passenger loads and heavy passenger buildup on station platforms.
Severe: Schedules are seriously affected. Passengers are advised to seek alternate transportation if possible with extremely heavy passenger buildup on station platforms and trains/buses arriving at stations/stops at capacity. Service will return to normal gradually (not immediately) when the issue is resolved.
Note: Rush hour periods can intensify delays.
Do delay alerts include the direction of service being affected?
Yes, it will be indicated within the alert if a delay is affecting service in one direction only. (Example: Red Line is experiencing minor northbound delays due to a disabled train.") In the event that both directions of service are affected, no direction will be indicated in the alert.
Will you share my e-mail address or phone number with anyone?
Does a T-Alerts subscription cost anything?
T-Alerts is a free service offered by the MBTA. Your cellular carrier may charge you a fee to receive text messages (SMS). Contact your carrier for details.
