Hello, I was wondering about the best approach to get data of a dynamic segment of a mautic instance to be added to a segment of another mautic instance on a different domain. Do we do it on database level, webhooks level, or is there some sort of api or maybe even a plugin that can transfer data between two mautics? Would love to know how to implement this in a robust way. Thanks ---

Hi, Some questions: What is the segment size? Why not to use 1 Mautic? How often is okay to synch? Daily? Weekly? Hourly? Upon request? Thx, J ---

I am fairly new to mautic. Can we use same mautic to send emails from two or more domains? If yes, then I guess I could use 1 mautic. Segment size would start from a few hundred and will potentially grow to thousands or even more down the line. I happy with syncing rate of once per week. ---

we run multiple instances for certain clients specifically due to the ESP limitation. In order to get around this we have setup some amazing stuff using [n8n.io](http://n8n.io) where data is passed through to different instances depending on actions like non/opens no/clicks, page hits etc… and then automatically added to different segments, Basically a monster operation running 🙂 ---

Yes, you can have multiple sending domains, there is a plugin for that. But in general I would go with @mikew 's suggestion. One more thing: with just a little coding you can also do automatic imports / export between instances using the custom import bundle plugin. It makes sense if you seal with 10k+ data at the time, since the custom import runs in 2 min, with webhooks would take more then 50x. Joey ---

Hey @joeyk for some reason I have not been able to get the custom import to run with the parallel flags. Any pointers ---

@mikew ive had the same issue since updating to 3.x. I change parallel import setting in local.php and then run overlapping crons as a workaround. ---

I never tested parallel imports. I’m not constantly running it, rather as a part of a bash script. 1. Make query and create csv 2. Run import. ---

I will have a look into it for sure. Thank you. ---

You’re right, i’ll first try @mikew 's approach and see how it goes. Thanks!
