Despite what a lot of SEO slop will try and tell you there’s no way to measure deliverability performance across multiple ESPs in any way that’s meaningful. (The SEO slop tends to do things like sign up for free accounts at a bunch of ESPs, send three emails to probe accounts and see how many reach the inbox at mailbox providers served by the probe account service. If you’re a...
I don’t send a lot of spam complaints generally. Mostly I block and move on. There are some companies, though, that I offer the professional courtesy of sending a complaint or a report to their abuse@ address. Former clients, friends and colleagues generally get that courtesy. The number of ESPs that completely fail to take any action is disappointing. Too many of them can’t even...
Last week news broke that Mailchimp had disconnected a number of anti-vaccination activists from their platform and banned anti-vax content. I applaud their decision and hope other companies will follow their lead in banning harmful content from their network. These kinds of decisions, where providers say you can’t do that on our network, are because these are private platforms. As I talked...
Over the last few years I’ve reduced the complaints I send to ESPs about their customers to almost nothing. The only companies I send complaints to are ones where I actually know folks inside the compliance desk, and I almost never expect action, I just send them as professional courtesy. The sad fact is, many ESPs are really horrible about dealing with spam coming from their networks. The...
There’s an ongoing discussion, one I normally avoid, regarding how much impact an ESP has on deliverability. Overall, my opinion is that as long as you have a half way decent ESP they have no impact on deliverability. Then I started writing an email and realised that my thoughts are more complex than that. Here are some excerpts from the email, because in other circumstances I would have...
The question came up on slack this morning about bounce rate benchmarks. What are the normal / average bounces that different ESPs see? Does region matter? What’s acceptable for bounce rates? Bounce rate is an overall measure of address quality Here’s your the chance for ESPs share the data from your customers. We’re interested in anything you care to share. But more detail is...
Last year a number of ISPs mentioned the Black Friday email volume was congesting their systems and causing delays. While anecdotally it seems that volume is up over last year I also haven’t heard any ISPs talking about congestion. Likewise, most of the delivery folks I’ve spoken too today and over the weekend are saying there were no major problems. How’d the busiest email...
There are probably hundreds of thousands of really awesome SaaS products out there. They provide a framework to do all sorts of stuff that used to be really hard to do. Almost all of them include some email component. They dutifully build the email piece into their platform and, because they’re smart, they outsource the actual sending to one of SMTP providers. They’re happy, their...
Last week, I talked about policy, using some different blocklist policies as examples. In that post I talked about how important it is that policy evolve. One example of that is how we’ve been evolving policy related to companies that get listed on Purchased Lists and ESPs. Who is listed has evolved over time, and we’re actually looking at some policy changes right now. Listing policy...
It seems silly to have to say this, but connecting on social media is not permission to add an address to your newsletter or mailing list or prospecting list or spam list. Back in 2016, I wrote: [Scraping addresses from LinkedIn] is really rude. Just because someone accepted your contact request on LinkedIn, doesn’t mean they want to be added to any mailing lists you may have. Let’s be honest...
