Email vs SMS vs Push

Choose the right communication channel for your message. This guide explains when to use email, SMS, or push notifications based on the urgency of the message, the intended audience, and whether workers are currently signed in on site.

 

What this means

  • Email is best for longer, non-urgent updates to supervisors and office-based recipients where you need detail and a record.

  • SMS is best for urgent, time-critical messages to workers who are currently signed in on the job site.

  • Push notifications are best for app-based reminders and alerts to users who have the mobile app installed and notifications enabled.



When you’ll use this

  • When you need to get a message to everyone who is actively on the jobsite right now.

  • When you need to notify a supervisor or site leadership about a compliance issue or event.

  • When you need to remind workers to acknowledge something in the app (depending on setup).



Key Notes

1.    Decide who must receive the message

  • Workers on site right now

  • Site hosts, supers, safety managers, or other site leadership

  • Office or company stakeholders

2.   Decide how urgent the message is

  • Immediate action needed (minutes)

  • Same day but not urgent

  • Informational / record keeping

3.   Choose the channel based on the match below

  • Use SMS when the message is urgent and needs to reach signed-in workers on the jobsite quickly (for example: drills, evacuations, time-critical site-wide updates).

  • Use email when the message is going to supervisors/site leadership, needs context, or should be retained as a longer-form record.

  • Use push notifications when you are relying on app-based alerts or reminders (for example: a reminder to acknowledge an in-app briefing), and you expect recipients to have the app installed with notifications enabled.

4.   Add the right “depending on setup” caveats in the message

  • If you use push notifications, note that delivery depends on the worker having the app installed and notifications enabled.

  • If you use SMS to reach “everyone,” be clear that it targets workers who are currently signed in on that jobsite.




Common Issues

People didn’t receive the message

What to check

  • Was the message sent via email, SMS, or push?

  • Were the intended recipients signed in on the jobsite at the time (for SMS site-wide messaging)?

  • Do recipients have the mobile app installed and notifications enabled (for push)?

What to do

  • If the message is urgent for active workers, resend via SMS to signed-in workers.

  • If the message needs to reach off-site leadership, send via email to the appropriate contacts.

  • If the message is an app reminder, confirm recipients are set up to receive push notifications, and consider using a non-push backup (SMS or email) when time-sensitive.



The wrong audience got the message

What to check

  • Was the intent “workers on site now” vs “site leadership” vs “company/office”?

  • Did the message include instructions meant only for supervisors?

What to do

  • For worker instructions that must be acted on immediately, use SMS and keep it short and action-focused.

  • For a supervisor-only context, use email and include the details there, not in the worker broadcast.




Why this matters

  • Picking the right channel improves response time during critical job-site moments and reduces confusion.

  • It also helps ensure the right people get the right information, without over-notifying everyone or relying on a channel that may not be enabled.

If you’re not sure which channel to use for your jobsite, contact your foreman or GC site team. They can confirm the preferred process for urgent alerts, routine updates, and app-based reminders.
