We are constantly improving our system and scaling our infrastructure dynamically based on the current consumption of our customer base.


If you have any specific requirements, please share them with us and your account manager will  get back to you.


As of today we haven't had a use case that our systems weren't capable of handling. Anyhow, certain routes and countries might have different rate limits and thus delivery speed may vary. The best method is to test and measure yourself and share the results with us.


If you send OTP or notifications in single SMS, then our system will automatically handle those with priority over larger campaigns.




If you have any questions, please send us an email at support@sms.to
