You should activate every email you specify as a "from" address. The activation is one-time for a single address. We insist on sender's email addresses activation to check the validation and avoid sending spam.

Now you don't have to register several service accounts for every of your email addresses to send messages separately from distinct address. Our service has all necessary functions for inserting and activating several sender's addresses to send email from. Besides, the number of such addresses is fully unlimited.

Keep the rules of email syntax, avoid spelling mistakes and extra whitespaces. Sender email address is a required parameter for every email campaign, so sender's name is no so important and can be discarded.

AtomPark Software guarantees safety of any data transferred via Atomic Email Service and non-proliferation of any information about its customers and partners without their consent.
