Email service provider (and event management offering) Constant Contact has made several interesting additions and enhancements to its overall service today. While we typically don’t feature general service upgrades and announcements of this nature, when a company has 350,000 users it is hard to ignore.

Constant Contact users can now share and reference .PDF documents, storing up to 5 documents or images for free with MyLibrary. Those seeking more depth can upgrade and receive up to 50 MB of document/image storage, plus a sample stock image gallery, for $5 per month with MyLibraryPlus.

“Having documents and images in a centralized location keeps content manageable and accessible, making it easier than ever to create fast and effective email and event marketing campaigns,” said Ellen Brezniak, senior vice president, product strategy, Constant Contact. “At Constant Contact, we are all about delighting the customer with product features and functionality that make online marketing easy and affordable.”

Constant Contact made some additional enhancements to its overall service with new capabilities and features include enhanced image editing and event themes and an improved contact management system.
