Ensure that the Provider Can Meet All Your Legal Obligations for Bulk Texting
Anti-spam filtering software at the content creation level has been successful in removing much of the stigma historically associated with bulk texting. However sending bulk SMS can still pose legal and financial risks – particularly with transmission across international boundaries.

For example, the greece telegram General Data Protection Regulation (GDPR) that applies in the European Union (EU) has strict guidelines in regard to bulk SMS. Specifically, organizations sending bulk SMS to recipients in the EU must provide a clear and obvious way to opt-out of receiving further marketing texts. What’s more, organizations must provide the opt-out clause using the same method of communication. As such, in Europe, you can’t, for example, send someone a bulk text and then ask them to send an email to unsubscribe.


Note that a standard text is 160 characters, including spaces. Any message exceeding this character count will attract a cost of more than one text credit. To conserve credits and retain focus on your bulk texting, you should stick to one clear offer or message with one simple call to action.

Bulk SMS messages often contain a link, inviting the recipient to click through to a website where they can respond to the offer. Be sure to optimize this landing page for mobile users.
