    If you have more than 2 people in your organization, then this will save you so much time. Delegation is the key to starting a business. Even when you're a 1 person show, being able to present to your user base the differentiation of options for client communications is critical. As a founder, feeling compelled to be always on is something I strive not to be. OpenPhone gives you that flexibility. I have found it to be less appropriate in complex HIPPA compliant areas, but that is it. OpenPhone really does seem to suit an open array of use cases.

    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.

    • 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

    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
    OpenPhone
    In my experience, App features are buggy and confusing, and they often don't match the descriptions and screenshots in their documentation. In fact, many of their help links go to 404 "page not found" errors. In my experience, there are frequent outages and quality issues. My customers prefer to talk to me on a different line, because they find it difficult to understand me on OpenPhone.

    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.

    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.

    Support Rating
    OpenPhone
    In my experience, their support feels like the opposite of support. They send you in circles, never directly answer questions, provide vague suggestions with unwanted platitudes, and they often take days between responses to provide that. For me, it's a frustrating experience that leaves you with a net loss of time and energy versus before you reached out to them. In my opinion, you definitely don't get "support".

    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.

    OpenPhone has an easier user interface than Grasshopper. Years ago when I was using Grasshopper, I recall that their user interface looked antiquated and full of complications. They would also update the interface just as everyone was getting used to using it. OpenPhone has many more functions. Grasshopper's app did not offer basic functions such as in-app texting between team members, and its call transfer function was incredibly complicated to use. In my opinion, Grasshopper was an inferior service/product in almost every way.

    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.
