Prepare your SMS Excel database and import it to create an SMS Marketing campaign

If your contact list is not yet refined, you will need to get up to date with the following steps:

  1. The phone numbers must correspond to each person and remain valid. They must also comply with the Data Protection Law when obtaining them. We explain more about this in this other post.
  2. Unify formats. You should not have phone numbers with different formats, nor a  combination of mobile and land line numbers.
  3. Eliminate land line numbers with Excel. You can go to the numbers column and then click on "sort and filter". Here you can create a custom filter; for example, see those that "start with 0 or 9". That way you will be able to delete all those that are fixed.
  4. Add the corresponding prefix. If they are numbers from Spain you can add the prefix 34 automatically. How?

For example: insert a blank column next to the mobile number column. Then, in the first cell of the column, enter the following formula: + CONCATENATE (34; A1).  Now all you need to do is click on the corner of the formula cell and drag it to the end of the database. This will adapt the prefix to all your contacts.

5- Eliminate duplicate numbers. The quickest way to do this is to duplicate the column with the list of numbers. Then look in "Data" and "Remove duplicates." Click there and you will have a new list with the good numbers. Later you can delete the original column.

We recommend you always work with copies, so if you make a mistake you will not delete your database by mistake.

6- Save the article. It can be in Excel or CSV format.

Once you have your database refined, to create an SMS campaign you will have to import your file to the LabsMobile platform.

Here are the steps:

Log into your WebSMS account

After registering a new account you will receive a welcome email containing the initial password. Access your account by entering your user name (registration email) and password at

Access the import form

Enter the AGENDA option - Import the file from the menu of your account. Here you can import a file with all the necessary data for subsequent shipments or campaigns.

 Download the template

At the bottom you can download a template (in Excel format) that you must complete with your database. Each line is a record consisting of name, phone number and other information.

 Group name

The name or group identifies all imported records. This group name is used to select, send and manage a specific database.

 Select the file

Once the file (Excel or CSV) is completed with the telephone numbers and additional data, it must be included in the form by dragging it to the corresponding area or by clicking and selecting the file.

 Optional parameters

The import process can eliminate duplicate phone numbers and delete all previous records so that the only phone numbers available are the imported ones.

 Confirm import

To finish, click on Import and confirm the operation. Once the import process is complete, the number of telephone numbers that were included in the account will be displayed.

 Display imported phone numbers

It is possible to see the contact groups of the account in AGENDA - Groups. By clicking on the name of each group you can view the data for each record.
