What's the best ESP?

I often get clients and potential clients asking me to tell them what the absolute best ESP is.
“You’re an expert in the field, which ESP will give me the best inbox delivery?”
The thing is, there isn’t an answer to that question.
ESPs have expertise in sending large amounts of mail.  All have staff that manage and monitor MTAs. Most have staff that provide advice on delivery issues. Many have staff that handle abuse complaints, FBLs and blocks.
What they don’t have is magic delivery fairies or bat phones into postmaster desks.
Simply moving mail to an ESP won’t give you delivery. For the most part, delivery is the responsibility of the sender, whether they send mail through an in house system or through an ESP.
Delivery is primarily about how recipients react to a particular mail stream. Send mail recipients want, interact with and relate to and you usually see good delivery. The IP addresses or infrastructure contribute but do not dominate the equation. Sending from an ESP won’t fix poor content, irrelevant mail or unengaged recipients.
I can hear everyone now shouting at their screen “What about shared IPs!!!?!?!” Yes, yes, if you use an ESP with shared IP addresses and the ESP gets a bad customer you may see poor delivery for a time because one of their other customers was bad. It’s a fact, it happens. Plus, if you use an ESP with dedicated IPs and the ESP gets a bad customer you may see poor delivery for a time because one of the other customers was bad and their IP is near yours.
So clearly the answer is to bring email in house. That way no other company can affect your delivery, right? Yes. Kinda.
Are you willing to invest money in hiring email and DNS savvy sysadmins? Invest money in a MTA designed to handle bulk mail? Invest in an expert who not only understands bounce handling, but can explain to your developers what a good bounce handling system must do? Invest in someone who can manage authentication like DKIM? Who can handle delivery issues and understands how to talk to ISPs? Invest in development to write a FBL processor?
For some companies, the internal investment is the right answer, and bringing mail in house makes business sense.
For a lot of companies, though, they just want to use email to communicate with customers. They don’t want to have to invest in multiple staff members (as it’s very rare to find a single person with all the various skill sets needed) to just send a weekly newsletter, or daily sales email. They need a tool that works, they don’t need to know how to sign up for a FBL, they don’t need to know how to handle bounces. They can outsource that work and focus on the communication value.
Finding the best ESP starts with finding out how you want to use email.
Question 1: What role does email play in my business?

You can't always get what you want

It’s a problem anyone who has done any delivery work has faced. There’s a client who is having blocklist problems or ISP delivery problems and they won’t pay any attention to what you say. They insist that you talk to the blocklist or the ISP or hand over contacts directly so they can “dialog with” someone internally. They don’t like what they’re hearing, and they hope that the answer will be different if they find a new person to talk to.
The reality is many of the people at ISPs and blocklists don’t want to talk to these types of senders. They may answer a friendly question from someone they know and trust, but sometimes not even then.
Some very large ISPs and major blocklists don’t even take sender questions. They won’t communicate with anyone about any delivery issues.
I’ve had to tell more than a few clients recently that various ISPs and blocklists weren’t interested in helping those clients with their delivery problems. There are two classes of reactions I get from clients. Some clients focus on moving forward. “OK, now what? How can we identify the issue, what data do we have and how can we figure out what the problem is?”
Other clients continue to look for ways to talk to whomever is blocking their mail. They’re convinced if they can just “explain their business model” or be told what they’re doing wrong, that all their delivery problems will magically disappear.
Needless to say those clients who focus on moving forward and looking at the information they do have have much better success resolving their delivery problems. What many senders don’t understand is the wealth of data they have that will help them resolve the issue. And even if they know it’s buried in their files, they don’t always know where to start looking or even what they’re looking for.
But that is, of course, why you hire someone like me who understands spamfiltering and email. I help senders understand how email filters work and identify what parts of their programs are likely to be responsible for delivery issues. I often find the most valuable service I provide to clients is a fresh set of eyes that can see the forest. With my help, they manage to stop obsessing unproductively about one particular symptom and focus on the underlying problems.
Senders who think the holy grail of problem resolution is speaking to the right person at an ISP or blocklist generally are disappointed, even when they hire someone who knows all the right people at the ISPs.  They can’t always get what they want. But I can often help them get what they need.
