I found Twilio to be excellent and very easy to use for a programmer in all aspects related to voice, SMS, and other features utilizing their API. I found the node client to be excellent and helpful. We previously used the Apex client for Salesforce before it was discontinued. Although we try not to use Twilio from Apex anymore, using that client was easier than implementing our own.
ZeroBounce is ideal for maintaining and improving your email deliverability. It's great for accurately processing large lists that contain many domains (not just the big box ISPs) and rooting out complainers. These results have the potential to reduce bounces before they happen, and keep your domain/IP reputation in good standing. ZeroBounce while exceeding expectations in email list cleaning, I would not recommend purchasing an email list, running it through their system and expect to be inboxing right out of the gate. Your deliverability is only as good as your list quality no matter how "clean" you think your list is.
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.
Segment’s email identifier is case-sensitive, which is ridiculous because emails themselves are not case-sensitive. This means that if I send a capitalized email address in an identify call, it will create a duplicate user rather than matching it with the lowercase email. I think this is a technical oversight that should be corrected.
I’d like to see more information about the eventual transition of existing Frontline customers to Twilio Flex
I’d like to see some integrations between Twilio Studio and OpenAI or another open source LLM to provide automated responses, if this hasn’t been done already
I would like to be able to drag and move the actual lines connecting the steps in Twilio Studio, sometimes mine can get pretty messy
I think a Bug Report form would be beneficial for developers
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.
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.
ZeroBounce is very simple to use. The interface is very user friendly. We didn't have to undergo any training or watch any instructional videos when we first logged in. There are little pop ups to highlight different features and explain certain things, but overall it's just upload a .csv and wait for the results. It then combines the results into one clean PDF breakdown, but it also gives more in-depth feedback through separate Excel sheets.
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.
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 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 such as Hotmail. However bulk checker email have blacklist that I'm talking about in previous question.
