Posted on (0 Comments)

No love has been lost for the National Security Agency after it was revealed that they were intercepting data between servers and computers. And it had yielded a strong response from Google.

What’s the difference between a hard bounce and a soft bounce? At SendGrid, we probably position soft bounces a little differently. We look at soft bounces more as blocks–or short term issues.
