We’ve been using SendGrid lately and have found it extremely useful. Their SMTP relay setup and flexible Web and SMTP APIs provide a simple integration approach for sending email. We have used SendGrid to solve a client’s frustrations with lost emails through their website. By sending email through two-factor authentication, multi-user credentials, API key permissions, IP Access Management, and more, we have made the email headaches go away.
If you’re looking for a helpful tool to solve your email problems, it’s worth looking into.
