The following are possible approaches to Bulk Mail.
Some churches send their data from MinistryPlatform to the mailing house for two reasons:
Use the USPS website to prep your mailings. This option allows you handle bulk mailing without a mailing house or software system.
See Intelligent MailĀ® for Small Business Mailers (IMsb)
This approach is useful primarily when using windowed envelopes where the name and address is printed right on the letter instead of on the envelope.
Load an export file from MinistryPlatform into your own internal mailing software to generate the labels, tray labels, and presort reports for the USPS. This is not much different from using USPS (above).
