How to set up automation in mailchimp?

Question

Automation

Introductory:
There is a site that delivers goods.
There is a discount that is valid for a repeat order within n days from the date of purchase.
There is an account on MailChimp from which mailing lists are regularly conducted.
Task: It is
necessary to remind customers m days before the expiration of the discount about its availability using e-mail. letters.
Problem:
We are trying to take the date of the last order as a trigger. Everything is fine, the trigger fires, but if the buyer makes another order within the period m, then the trigger is not updated. I.e.:
The user places an order on 01/01/2015. The trigger fires, the user queues up to send a discount email on 01/11/2015 (10 days later).
The same user places an order on 01/05/2015. The trigger is not updated, it is still in the queue as of 01/11/2015.
Has anyone encountered a similar problem? How to solve it?

Answer 1

As far as I understand, now you have a queue for sending an automatic letter in advance and therefore a further change in the value of the "date of the last purchase" does not prevent sending.
It is necessary that the dispatch queue is formed on the day of dispatch.
For example, you can give Chimp not the date of the last order, but the date + 10 days.

Answer 2

Good afternoon.
In your case, the task is quite difficult for Automation MailChimp, because the original parameter - the date of the last order - changes.
Try sending such a reminder via https://www.mandrill.com/ - MailChimp's transactional messaging app. There you can set any sending conditions using the API.
