Just to give all of you an update. As of late I have been dealing with a bunch of Russian hackers who have decided to spoof and spam hammer with my domain.
Even with DKIM and some other protections in place this has taken a toll on my IP and Domain reputation which has slowed my deliver ability considerably.
Therefore, I have had to refund a number of solos
As a business decision I have decided to close for new orders until I can get new IPs and a domain warmed up.
Thank you for your understanding,
After being both buyer and seller for many years I have to say my personal preference is to leave traffic unfiltered, provided that it is not fake or duplicate clicks.
I have seen sales come in from some very remote countries. I have seen sales come in from proxies and other traffic classifications as well.
Moreover, I think in general pure T1 is just overpriced from a buyers perspective.
I understand why a seller would charge what they do because there are higher costs associated with acquiring and extracting it.
In general lists here on Udimi are mainly built on English speakers so just on that fact alone you are going to get very high rates of T1 without paying extra.
With regard to Mobile. Remember today there is more mobile traffic then desktop today. So instead of filtering it I would highly encourage you to make sure your funnel is optimized for it.
My 2 cents from being in the field all this time.
