Synchronize your contacts
Learn how to do a proper script to synchronize your contacts between your Ownpage contact list and your own database.
The recommended solution is to consider your database as the source of truth and replicate new subscriptions and new unsubscriptions to the Ownpage database. The steps are the following :
- Extract all subscribers from Ownpage database
- Extract all subscribers from your database
- Subscribe in Ownpage the users which are subscribed in your database, but not in Ownpage's
- Unsubscribe in Ownpage the users which are subscribed in Ownpage's database, but not in your's
The code bellow is an example and should be adjusted to match your needs.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65
Using this solution, your newsletter must have a unsubscription link pointing to your website and directly updating your database.
Not recommended solutions
Subscribe/Unsubscribe users without checking the diff
You could call the Ownpage API as soon as a user subscribe or unsubscribe on your website. This solution could work just fine but you would need to be very careful about error handling.
If for any reason, a request made to the Ownpage's API fails, you should be able to retry the action until it succeeds. If done badly, the risk is to desynchronize the two databases. E.g.: your system calls Ownpage API to unsubscribe a user but it fails and does not retry : we will still send emails to this user despite being unsubscribed in your database.
Remove everything from Ownpage's list then duplicate your database
A quick way to sync your Ownpage's list with your database would be to clean everything from Ownpage list before loading again every subscribed users. That way, you are certain that the Ownpage's database is same as your's, and you don't have to get every subscribers from Ownpage to make a complicated diff.
Deleting subscribers each time will also delete attached data, like the dates at which the user has opened or clicked in your newsletter. You will loose behavioral information on your subscribers, and the ability to filter based on subscribers activity (eg: send only to users who have opened a newsletter in the last 30 days)
