This is the way our email notification system works: lets say, you are a coffee seller and there are 184 coffee buyers subscribed in our directory. If you update anything in product details (price, packaging, quality, etc.) information about this modification will be registered. Overnight, all changes will be processed and consolidated and the 184 coffee buyers will receive an email, including a notice of any changes and a link to your company profile.
If you are a coffee and cocoa buyer: you will receive only one email, informing you about all changes concerning both products.
This system guarantees that all registered subscribers receive no more than one email a day and also that the message informs them only about the changes related to their own products. The targeted emailing system means that you will not need to waste time constantly checking for updates.
