Does the geolocation of mailing IP's actually matter? For example, if I'm mailing US data but using IP's from the UK or something like that. I know it used to have a small effect in the SEO world (location of server vs regionalized SERPS) - so it's possible it might somehow impact deliverability, if only to a small degree. Anyone have experience with this?
It depends on your target audience. If you're hitting GI then the location of your IPs may play a role in delivery. From my experience with yahoo, aol and hotmail I have not seen a geo location of the IPs matter.
I agree with Nick. When mailing Yahoo/AOL/Hotmail, IPs from ARIN or RIPE work just as well. I can't speak for other registries.
That's what I'm thinking. These would be western Europe IP's in particular so I think we'll be ok. As usual, test test test. If I see any strange / unexpected results I'll post back.
Aside from these "bad/blocked countries" you are also going to have the issue of network latency if you are mailing from IPs/servers across the globe from the receiving domains. That in itself is going to affect your results.
My thinking was that if there's a latency sending the emails it shouldn't really be a problem - I'd be far more concerned if our tracking domains / offers were being hosted around the globe. A short latency sending the emails themselves *shouldn't* be an issue, unless I'm misunderstanding something?
It will honestly depend on where you source from and the port speeds offered. We've dealt with ISP's all over the world, and most of the time it doesn't effect deliver-ability. You send from here, it tunnels to Romania, Germany, Netherlands, UK, Argentina, Brazil, Panama, China, Philippines, Hong Kong, and then emails back to the U.S. and people can mail with little grief. You simply have to make sure you have enough juice/bandwidth. I'd recommend a 100Mbit or 1G port for better performance for those long distances. But there are people with a standard Dual Core and a 100Mbit port with 10Mbit unmetered who operate just fine. Keep in mind.... outside of what's generally considered 'the western world' bandwidth is not always so cheap. Plan accordingly.
Thanks for the advice! It's appreciated. I'll ask the ISP about the bandwidth / port speed. They seem top notch but good to make sure we've got our bases covered.
Latency is always an issue - you'll get more connections slowed or dropped. Try throttling your network by hand and see what happens to your delivery / revenue.
