SMS settings: connection, callback URLs, numbers, delivery reports and DLT on one page.
On your own gateway
Settings shows two Callback URLs:- Delivery reports — sent with every message automatically. Nothing to set up.
- Replies (inbound SMS) — give this to your gateway provider so replies reach your Inbox.
Send SMS
SMS → Send SMS sends straight from the channel.1
To
Type numbers, pick contacts, or pick segments. Up to 500 numbers and contacts at a
time; for more, upload a file in a broadcast. Picking a segment
makes the send a broadcast, sent in the background.
2
From
Pick one of your approved sender IDs. Where your provider doesn’t require approved
sender IDs, you can also leave it on your gateway login’s default.
3
Message
Use a template and fill in its blanks, or Write a message. When your account
sends approved templates only, the page says so and offers templates alone.
4
Check and send
Under the message, OMNI shows the encoding (GSM-7 or Unicode), the length, the number
of segments, and how many messages that makes for everyone you picked. A preview
shows the message as it will arrive. Confirm to send.
- Send later — a date and time. Until then you can cancel it or send it early.
- Keep trying for — how long the carrier retries a phone that’s off: the carrier’s default, 1 hour, 6 hours, 1 day or 2 days.
- High priority — for codes and alerts that can’t wait.

Send SMS: recipients, sender ID, template or free text, and a live preview.
The SMS dashboard
SMS → Dashboard shows what the gateway reports live and what OMNI logged, over the period you pick:- your gateway balance, live;
- Submitted — messages and segments, with an estimated spend;
- Delivery rate, and how many failed;
- Traffic — submitted and failed over time;
- What the carrier said — the delivery report status, kept exactly as the gateway gave it;
- Top failure reasons and Recent campaigns;
- Registration health — your sender IDs and templates by status. Only approved ones are offered when you send.

API & playground
People who can configure channels also see API & playground, when the plan includes API access: the SMS gateway’s own API with its documentation, a live runner and code samples. For sending from your own software, most integrations use the OMNI API instead, which also manages sender IDs and templates.Replies, opt-outs and limits
- Replies arrive in the Inbox in the person’s SMS thread.
- STOP stops a person on every channel; do-not-contact and quiet hours are always honoured. With the Customer data battery, people can stop SMS alone, or SMS marketing alone.
- When your provider enforces approval, a message from an unapproved sender ID, or one that matches no approved template, is refused. See Sender IDs and DLT.
