Bulk Mail Merge
Send personalized letters
to everyone on your list
Upload a CSV, write your message once with merge tags like {{first_name}}, and we handle the rest — printed, sealed, and USPS-delivered with tracking.
Bulk orders are placed on our sister site, SentInstantly. Upload your CSV there, write your letter once with merge tags, and each recipient gets their own printed letter, up to 1,500 recipients per upload.
