Setting Up SMS Processing

You can send SMS messages through your service provider using processing in our system. For that, you have to configure the sender settings in your profile.

Configuring the Sender Settings

To configure SMS processing for registered senders:

Go to your profile → Settings → Senders.
Select the SMS tab and click the New sender button.

In the slide-out window, select the I’ve already contracted an SMS service provider and have a registered sender option and select your service provider from the list:

GMS Hyber
Infobip
TurboSMS
Omnicell
Textlocal
Acemount Media
Twilio
SMSBAT
Streamtools
Vodafone
Intel Telecom
PROCONTEXT
Decision Telecom
AlphaSMS
ServerSMS
SMS Club 2.0

Enter the required technical parameters of your provider, as listed below:

📘
Note
The Sender name is an internal name displayed only in your account — it doesn't affect delivery and can be any value. The alpha name that recipients see as the sender must be registered with your SMS provider; sending with an unregistered alpha name isn't possible.

GMS Hyber

Sender name
Login
Password
URL
Timeout

Use Yespo tags so that when uploading reports from GMS Hyber, you can quickly analyze how many messages of a specific type were sent: collecting feedback, installing an application, etc. If you use more than one tag in a message, they are substituted in the report separated by commas: tag=tag1,tag2,tag3.

📘
Note
Ask GMS Hyber to add the 52.210.222.17 and 52.16.166.210 IP addresses to the allowed list.

📘
Note
SMS Club 2.0 is a new version of the SMS Club API integration. It appears in the system as a separate provider and will gradually replace the previous integration version.

In SMS Club 2.0, processing is supported for both Viber and SMS.

To switch to SMS Club 2.0, SMS Club must migrate your account from the previous system to the new one.

After the migration on the SMS Club side, you will need to select the new provider type — SMS Club 2.0 — in Yespo and update your access credentials.

SMS Club 2.0 uses an authorization token instead of a login and password.

SMS Club 2.0 supports Viber carousels. This option is not available in the previous integration version.

Click Done.

Now, you can proceed with creating and sending SMS messages. Read this article to learn more about it.

📘
Note
The team isn't aware of any systemic delivery issue with Android spam/junk filters affecting SMS. Cases like this are treated as device- or carrier-specific rather than pointing to a platform-wide problem.

SMS Click Tracking (Short Links)

When link tracking is enabled for an SMS, Yespo wraps the original URL into a short link on the default esclick.me domain. By default this can result in a longer link than generic shorteners like Bitly, which adds to the SMS character/part count — factor this into message length planning.

To shorten the link, add your own custom domain for link shortening — this is an account-wide setting that applies across channels, including SMS, and lets you use a short domain of your choice instead of the default one. If link length is still a hard constraint for a campaign, you can also omit the tracking wrapper for that specific link, though this disables click statistics for it.

📘
Note
Keep the https:// protocol in SMS links: without it, many mobile messaging apps do not render the text as a clickable link.

The Unknown Status

Unknown is an intermediate status: the SMS provider hasn't yet returned either a delivery confirmation or an error for the message. The final status can appear later — providers may return it with a delay — after which the status updates, for example, to Delivered.

The SMS_GENERAL_ERROR Status

SMS_GENERAL_ERROR can mean that the recipient's number is in the mobile operator's blacklist — for example, after the subscriber complained to the operator. To find out the reason and remove the block, contact [email protected].

The SMS_UNDELIVERABLE_STATE Status

SMS_UNDELIVERABLE_STATE is a generic non-delivery status returned by the SMS operator or provider, not a single detailed reason. It can stand for a non-existent or blocked number, a switched-off phone or no network coverage, an unsupported country, or other provider-side causes. To find out the precise reason, look the message up in your provider's own logs.

📘
Note
One case is worth checking first: if a newly created alphanumeric sender ID is still awaiting operator approval, every message can come back with this status until the approval lands. Approval takes at least two weeks, so re-test after two to three weeks.

Deleting a Sender

To delete a sender:

Go to your profile → Settings → Senders.
Select the SMS tab and click the Delete icon at the right-hand side of the sender name you wish to delete.

On the dialog window, select Delete. The confirmation message appears for a short while.

Important

Before deleting a sender, you need to create or select another one, otherwise, you will be unable to send messages.

📘
Note
Deleting a sender does not reliably stop SMS sending on its own. The sender name is copied into an SMS message at the moment the message is saved and stays in it as text, so triggers or API calls referencing that message can keep sending via SmartSend even after the sender (alpha name) is deleted from the account. To stop such sending, stop the API requests on the integration side or delete the corresponding SMS messages in your account. To reliably stop all SMS sending for your account, contact support — this needs to be handled at the account level rather than through the sender or message settings in the UI.

Changing an SMS Sender

To change a sender in existing SMS messages:

Go to Messages → Messages → SMS and select an SMS.

In the Main settings section, expand the dropdown list below Sender and select another sender for this message from the list.
