    We have used two companies: Bulk Checker Email and Validity.com. We stopped using Validity.com because it became too expensive for what it offers. Bulk Checker Email is very slow and often experiences accuracy issues and frequent outages, especially with some mailbox providers …

    Our early experiences with SparkPost were great; we were looking for a low-cost (or no-cost) solution to our email messaging needs, and SparkPost had the best low-cost option: 100,000 messages per month for free, guaranteed for life. Even though our team has experience with other APIs, we chose SparkPost because it felt like the best value. Our experience with it was great. Two years ago, they discontinued their free option but sent the existing users the following message: "When you signed up, we promised that if we ever changed the terms of our 100K free plan, we would continue to honor the original plan for the life of the account. I would like to reaffirm this promise: while this plan is no longer available to new customers, you are grandfathered into this level of free sending volume." The following year, apparently following a change in leadership, they decided to "deprecate" existing free plans, dropping us down from 100,000 messages per month to 500, the lowest of any email API service I'm aware of. No recognition of the broken promise, the reneged guarantee, just a 20% off coupon. This atrocious behavior that reeks of a new culture of squeezing as much money as possible out of its users and has coincided with a steady deterioration of functionality and customer service. At this point, I have no idea why anyone would pay more for a worse service that treats its users so poorly when you could use SendGrid or a similar competitor for a lower price and way more features.

    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?

    Pros

    • When you don't want to spent time writing your own code to send emails from your apps
    • When you're looking for a product which provides all that you need regarding email features to make it part of your software
    • When you want to use a product which includes templates that can be re-used instead of writing your own and all the required effort to do that

    • 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.

    Cons

    • When I first implemented SparkPost, I did not take advantage of the sub-account feature, and my account was suspended on New Year's Eve. It took two days until I could speak with a support representative to get my account re-activated. I am now using sub-accounts to alleviate the underlying problem, but I was disappointed that my account was suspended by an automated system with no notice.

    • 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.

    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.

    Would give it a zero if I could. Their customer service used to be incredible; fast response times, really hands-on with their users, and a pretty regular feedback process. They sent me an awesome t-shirt that became part of my go-to climbing gear. But for the past year, their response times went way down, their customer service was less helpful and generally a lot more rude, and they haven't asked for customer input once since their leadership change

    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.

    Mailchimp and sendgrid are giving good services and good customer support 24/7 and ROI is increased with this as transition is very smooth. SparkPost is very expensive and not good as much as we think and they will least worried about your mails, tickets, call and messages. Highly not recommended this SparkPost to any one

    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.

    • Our deliverability is approximately 99% on most emails we send thanks to ZeroBounce
    • We've had an increase in our domain reputation
    • The price is affordable and similar to other tools that do the same, but are not as accurate as ZeroBounce
