PromoSMS is an SMS and mobile marketing provider based in Rybnik, Poland. Its core services include bulk SMS, MMS, SMS API, Email2SMS, SMS2SMS, and SMS receiving. The site says it has years of marketing experience, processes a large volume of SMS messages each month, and offers a 14-day free test account.
In terms of channels, PromoSMS is mainly focused on SMS, while also offering MMS, Email2SMS, and SMS2SMS. No voice or IM capabilities are mentioned. For coverage, the site claims service availability in 194 countries, but the API documentation also states that certain message types, such as SMS ECO and SMS Flash, are limited to Polish domestic operators. International numbers must include the country prefix, so actual channel availability needs to be confirmed by country and SMS type.
API and integration are among its strengths. REST API 3.2 supports SMS sending, delivery report queries, reply collection, balance checks, message conversion, and number validation. It supports JSON/XML, delivery-url callbacks, custom message IDs, scheduled sending, custom sender names, and more. For medium to large bulk sends, the documentation recommends submitting 50-200 numbers per request. On average, the platform hands messages over to operators about every 15 seconds.
The text does not disclose specific SMS unit prices or packages. It only confirms that the API is free to use, Email2SMS is provided as a standard free feature, delivery reports are also included as a free standard feature, and account balances are displayed in grosz. Sales and customer support are available by phone and email, but there is no visible SLA, online ticketing system, or 24/7 support statement.
The advantages are detailed API documentation, a fairly complete feature set, support for delivery receipts, and SMS ECO replies. It is suitable for marketing SMS in the Polish market, system notifications, collecting customer replies, and developer integrations. The drawbacks are the lack of public pricing, payment method information, delivery rate metrics, and compliance details. The site is primarily in Polish, which raises the barrier for international teams, and some SMS types are restricted to the Polish local market.
Mainland China access, payment availability, and ICP/cross-border compliance information are not covered in the text, so these should be considered unknown. If you need to send SMS to Chinese users, it is better to first evaluate local alternatives such as Alibaba Cloud SMS and Tencent Cloud SMS. For European or Poland-focused outreach, PromoSMS can be considered as a regional SMS API option.
