    I have tried other competitors. But I always end up going back to Twilio because I feel like it is dependable, easy to use, and, has competitive pricing. The only time I wouldn't recommend Twilio to someone as if they are completely inexperienced about using webhooks or APIs. Because you can't really just sign up and start using Twilio without connecting it to another platform first.

    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
    Twilio
    • Easy to see my team in one place, when they log in and out and what call status they are in.
    • Twilio is a simple, user friendly way to log in and out of work activities.
    • Excellent services and support.
    • The omnichannel feature which allows agents to get request from all channels.

    • 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
    Twilio
    • Control panel. Often, navigating through lists is challenging. I want endless scrolling, not pagination.
    • Conversational intelligence service require a Language. I would like it to detect it.
    • We would like to have some credit on clients that chose to use their own Twilio account.

    • 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.

    Unless we can get this handled quickly -- less than 1 week -- we will likely switch to another provider who, in my opinion, we'll have to spend close to $3,000 in development time to build a new integration for texting. Our clients need texting and I feel Twilio has failed us miserably.

    Usability
    Twilio
    Twilio has well documented APIs and examples. There are several tutorials, videos and Q&As regarding their services. So, usability is very good. I must say that advanced knowledge of telephony, API/Programming and error-handling is essential to make good use of Twilio. It's not just plug-and-play unless you are integrated with a system that has all of the programming built for it.

    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.

    Performance
    Twilio
    Twilio executes what it is designed to do: send SMS messages at scale while providing very good deliverability. I believe that Twilio is very good at what we use for adding SMS messages to our comms strategy. We can see those messages get opened and replied to, which is exactly what we are looking to achieve.

    Twilio
    I have not had to communicate with Twilio support in the last 3 years but my past experience with them has been very positive. They replied to my previous requests promptly and kept me well informed to resolve my inquiries. With their documentation that's available, I hardly imagine why anyone would need to contact support since it's all there in a concise and easy to understand format. It would probably take you longer to type out a support ticket than to just open their doc websites.

    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 evaluated many fundraising-based text-to-give programs and found the subscriptions prohibitively expensive for our small scale and uncertain first few years of development. While we may be willing to invest that kind of money after discovering how things work, we're happy with Twilio now and have no desire to start over.

    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.

    Return on Investment
    Twilio
    • We found that associates who had the opportunity to respond to a survey about their assigned job were 37% more likely to return to a job site
    • We were able to reduce the number of resources required to manually respond to associates using Twilio Studio, so those resources could have more time to complete other tasks
    • We were able to scale the number of associates who received survey messages at least by a factor of 8 without increasing our resource demand

    • 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
