Bulk SMS

Bulk messaging with quality

Bulk SMS is often equated with spam, but this does not have to be true. Extensive bulk messaging can also be quite informative and useful – for providers and recipients. You can, for example, send out newsletters for certain categories of an online shop, do a lottery or let customers vote on a product.

As a company, you benefit primarily from a strategical and well-distributed customer relationship. For your marketing communication, this means that bulk SMS are especially valuable, because thanks to our specially configured products your SMS don’t end up in the recycle bin or at non-active numbers. They arrive directly, quickly and reliably at your selected customers’ phones.

Because we value intuitive transparency, we offer you full cost control as well as statistics that help you to evaluate your messaging.

Send Bulk SMS in a breeze

Automatically reliable, fast and easy

Of course, you do not have to enter each message individually. To send bulk SMS, we recommend our seven-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, you can easily organize standing orders and track deliveries in the log file.

In addition, you have several two-way massaging configurations to choose from. Use Email2SMS to send SMS for example. A return channel can also be set up quickly and easily. For our inbound system, we will gladly provide you with physical or virtual telephone numbers. These enable you to receive answers, that you could use for service or product evaluations, among other things.

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 are subject to value added tax at the statutory state. Prices for non-EU countries may vary. Please check our full price list by country. 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 is then for 70 characters. No transmission to special call numbers.
