Is there a limit on the size of the emails created with offline replication

We are looking at using Interbase Replicator for offline replication using email. Some email providers have limits on the maximum size that an email can be. If there were a large number of database changes to replicate, would your software always put all of the changes into one large email, or can it be configured to put the changes into a number of smaller emails. Thank you for your help.
