Co-manager of a web agency, we have been using CaptainVerify services for several years and there is no need to say it is essential and above all the tool is great! The ergonomics and simplicity of the platform are a real plus, and we have no more concern for deliverability. This allows us to wash the basics of our customers (emails and mobile numbers) and thanks to this more mass sending accounts blocked due to poor deliverability. An essential if we use the email and sms channel!
