Bulk SMS

Bulk messaging with quality

Often bulk SMS is equated with spam, but it doesn’t have to be so. Extensive dispatchers can also be quite informative and useful – for providers and recipients. Be it the subscribed newsletter to certain categories of an online shop or the voting for a profit game. As a company, you benefit primarily from a strategically well-distributed customer relationship. For your marketing communication, this means great value, because thanks to our specially configured products your SMS don’t end up in the recycle bin or at non-active numbers, but directly, quickly and reliably at your selected customers.

Transparency and professionalism with every SMS

To send bulk SMS we offer you optimally developed API applications. In order to use this, you have several interfaces to choose from which you can integrate your own software with our SMS gateway. This gives you access to your familiar features as well as all our modules, including the complete overview via address book, delivery report, log files and much more. For a correspondingly intuitive transparency we allow you full cost control up to statistical evaluations of your notifications.

Automatically reliable, fast and easy

Of course, you do not have to enter each message individually. To send bulk SMS, we recommend our sms77-cli tool. This allows you to send SMS manually or automatically via the command line. Either enter the parameters directly or save them as a config file. For example, so you can easily organize long-term orders and can trace the transmissions in the log file.

In addition, you have several two-way massaging configurations to choose from. Be it SMS2Email or Email2SMS – also a return channel is set up quickly and easily. For our inbound system, we will gladly provide you with physical or virtual telephone numbers, via them you can receive answers, for example for service or product evaluations.

Transparent and fair – Prices to send SMS

Simply top up your credit balance and pay only the SMS you send. There will be no additional costs for you. All features like the API, Email2SMS etc. are available free of charge for each account.

*All prices plus 19% VAT. The prices are valid for a sent SMS with 160 characters. Messages with more than 160 characters are calculated according to the number of sent SMS, in which for each SMS message 8 characters less are available. An SMS with e.g. 310 characters would thus be calculated with the triple SMS price. For SMS with unicode characters, ie characters which are not included in the standard GSM alphabet (e-g. cyrillic, arabic, etc.), only 70 character per SMS are possible. The price above then applies to 70 characters. No transmission to special phone numbers.
