This is a small app update. A user wanted to be able to divide their Mailshot groups up into subgroups matching the size limits imposed by their email provider (typically 100, 50 or 25).
You could already divide into subgroups of 100, but now you can change the size of these groups to match your provider’s limit.
Enter your desired limit into the “Subgroup size” on the Mailshot page in Settings (the default is 100). Now when you select a group, tap “More…” and then “Split”, it will create a series of smaller groups of that size or less, and will rename the existing group by appending “-ALL” to its name.
