Agree, to find out about special conditions or fantastic discounts for the goods that you so wanted to buy is very cool! But it's great only at the exact moment when you need this information! What is the use of e-mail with a welcome offer, if the deadline for this offer has already passed? This newsletter will only upset the user.
The impossibility of managing the time for obtaining information is the main problem of all modern channels of marketing communications.
This has led us to introduce a mechanism that controls the relevance of your mailings. When creating a push notification with a limited time offer, you just need to specify the activity duration of this message. If the user does not read this message within the specified time, he will not receive it!
We recommend you always set a validity period for messages so that the user who has not used the Internet for a long time does not receive the whole chain of your messages.
