fixes https://github.com/TryGhost/Team/issues/2522 When sending an email for multiple batches at the same time, we now reuse the same email body for each batch in the same segment. This reduces the amount of database queries and makes the sending more reliable in case of database failures. The cache is short lived. After sending the email it is automatically garbage collected.
