I've been using Markopolo for a few weeks now and they have one of the best support team! They reply in a quick manner. I can even schedule calls with them. Rubaiyat and the team are very patient with me too.

The feature I like the most is it's ability to target users in a specific location. I live in a country where Facebbook doesn't segment users to a specific loation, but one country as a whole. And this feature is a game changer.

Markopolo, as of now, doesn't have the feature for me to upload creatives based on placement. However this is in the roadmap and I'm looking forward to this feature.

Overall, great team and the app has a huge potential! Tier 1 is great for small business doing their ads in-house. Tier 3 is great for agencies. I highly recommend this.
