You have several choices when selecting to who send your campaigns:
You can select them from a contacts list already saved on our platform;
You can select several contacts lists at the same time when preparing your sending;
You can write down the phone numbers of your clients by separating them with a coma;
You can import a contacts list from your computer (CSV or TXT format only).
You will find those options when preparing your campaigns in the “Selection of the recipients” section.
