SMS notifications
Get a text when it matters most.
Overview
When an urgent incident hits (your site goes Down, or a page fails its content check), you need to know now, not when you next open your laptop. SMS notifications send a text straight to your phone, so you can act before your customers even notice something's wrong.
Plan availability
SMS notifications is available on Pro and Business. See the plan comparison.
SMS is per-user: each member adds and verifies their own mobile number, rather than the team sharing a single number. Your plan sets how many people can hold an SMS seat at once. Pro and Business each include a set number of seats and a monthly message budget. See the plan comparison for the exact figures.
SMS works alongside email and Slack, not instead of them. Your team still gets email alerts and Slack messages (if connected). SMS means the person on call gets a text in their pocket, not just a notification in a browser tab.
Setting up SMS
There are two steps: verify your own number, then take an SMS seat.
- Make sure your team is on Pro or Business
SMS is included with Pro and Business plans. Check your team's plan in your billing settings, and upgrade if you need to.
- Add your mobile number on your profile
SMS is per-user, so you verify your own number. Head to your profile, find the Mobile number section, and type in your number including the country code (e.g. +44 for the UK). Request a verification code.
- Verify with the code
You'll receive a six-digit code by text message. Enter it to confirm the number is yours.
- Get a seat, then opt yourself in
This is a two-part step. First, an owner or admin gives you a seat from the SMS seat list on Settings → Notifications (it shows how many of your plan's seats are in use). Then you opt yourself in on Your notifications (avatar → Profile → Your notifications), where an SMS / Incidents toggle appears once you hold a seat.
Didn't get the code?
Double-check you entered the right number with the correct country code. If it still doesn't arrive after a minute or two, try again. The code is valid for a short time, so enter it promptly.
What triggers an SMS
SMS notifications are reserved for urgent (P0) incidents only: the kind that need someone's attention right now.
| Notification | When it's sent |
|---|---|
| Urgent alert | A site goes Down, or a page fails its content check |
| Resolved | The urgent incident is over and the site is back to normal |
Lower-severity problems (slow responses, certificates expiring soon) are handled by email and Slack. This keeps SMS for genuine emergencies only — so when your phone buzzes with a DomainDash text, you know it's real and worth dropping what you're doing for.
Recognising DomainDash texts
SMS messages are sent from the DomainDash sender identity. Any links in the message use the short URL dash.support to keep texts concise, and they link straight back to your DomainDash dashboard.
Managing your SMS
Once you're set up, you can manage SMS from two places.
Opting in or out
Open Your notifications (avatar → Profile → Your notifications). Once you hold a seat, an Incidents SMS toggle appears, and you can opt yourself in or out of incident texts. Opting out frees up your SMS seat for someone else on the team.
Changing your number
Your mobile number lives on your profile. To change it, disconnect the current number there and verify the new one. Because the number is yours, it follows you across any teams you're a member of.
Seats across the team
A team owner or admin manages the team's SMS seats from the notifications page; they can see who holds a seat and free seats up if the team is at its limit. The number of seats is set by your plan.
