If email deliverability is important, then Postmark is king. I've used all sorts of providers, with dedicated IPs and without. Postmark has always had the best deliverability and has resulted in the least amount of customer service time wasted dealing with users who simply did not receive an important email from us. It is pricier than other options, but it's well worth it if deliverability is at all important to you.
At the outset of my position with my current company, we used a marketing automation system that was known as a swiss army knife: it could do many things, but none of them well. They had no built in functionality for boosting email deliverability. Digging in to find out what we could do to improve our authority, we learned we needed to clean our lists before sending. ZeroBounce does everything we need it to, and at a reasonable price. What more could you want?
Bulk List validation up to 25 IDs per action is useful in some situations, as we don't want to create a CSV file every time, and for this smaller number.
We sometimes use the email Finder option when we can't find an email for a person on any other platform.
Navigating among bulk validation, CSV upload, and single-ID validation is hard, and sometimes finding them or switching between them can be made more user-friendly.
Results: After bulk validation, we receive the results in a Zip file, which is useful sometimes but not every time, as we have to un-zip, and there will be a different CSV file for each result. The final results can be made simple, like email ID in column A, results (valid or Invalid) in column B.
The only thing that confused me initially was that if you don't put a specific sender email into the Wordpress plugin settings (I use Postmark exclusively with Wordpress site), it won't send emails. I thought that having selected the option to send via any @domain.com email, I wouldn't need to fill out a specific email to send from, but that isn't the case. I sorted that out quickly with support.
For the large suite of services that they offer their system is pretty easy to understand and navigate. ZeroBonce is also NOT one of those services that is constantly tweaking their UI and making it hard to find tasks that you regularly use. More complex tasks can be more challenging but that's understandable. They also have an extensive restful API that if technical enough allow you to automate some of your most used tasks. They stand behind their product with good documentation as well as high quality customer service.
Postmark has been an excellent solution for our business needs. We have been with them for years and have no intention of changing providers anytime soon. Support was excellent as we were getting started and their API documentation made implementation quick and easy
We have used ZeroBounce for about 18 months and it works flawlessly. We are able to get all of our questions/issues answered immediately. Felt very comfortable with the product immediately - used their web site which walked us through it and were able to get up and running within minutes. I really haven't had any issues that required support.
We felt Postmark's focus on transactional emails and their use of shared domain reputation made them stand out. We also like their user interface and ability to have many virtual email servers. Pricing was competitive and after a trial we saw a big increase in deliverability rates. Therefore it was an easy decision to use Postmark over other providers.
We considered AtData since it was recommended by a colleague who has used it in the past. We ultimately ended up going with ZeroBounce based on the cost and documentation/resources available. Email validation tools are probably very similar, but ZeroBounce seemed the simplest for us, and we needed to implement one fast, so activation time was very quick.
