In my opinion, sendgrid is complete garbage compared to Postmark, it's not even a comparison. I had issues with emails being sent to spam using sendgrid IPs. The dashboard is inferior, the setup is fairly comparable in difficulty, and ongoing visibility is inferior.

Chose Twilio
I’m using or have used these services. I like to try multiple applications. I’ve selected Twilio because the documentation in C# is amazing.
ClickSend supports live chats, where instant messaging is done for both formal or informal discussions. Besides, proper management of tasks, from the simplified ones to the complex ones, and every player is well assigned. The option of bar code in this application ensures there is the automation of many tasks and reduces paperwork.
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.
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.
You can add list of users just by uploading numbers CSV or by uploading detailed CSV.
You can generate quick campaigns just like in email, save templates with URLs, send immediately, or schedule for a certain date and hour. They have analytics, shared, and private numbers. I like that it is super straightforward.
You can make automated campaings that will be sent every time a new user joins a list. This you can do with 3rd-party integrations such as your own app or Zapier since ClickSend already has this integration.
Super cheap and it's what I like most. You pay for SMS in bulk with really competitive prices. Most SMS companies want to charge by the number of users, and when you have 32,000 active users or +130,000 users it just becomes expensive so ClickSend is the SMS solution.
In general, using ClickSend is quick and the learning curve for new users is flat since it's almost the same as an email marketing tool just for SMS and compressed.
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.
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.
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.
In general, support is good. Actually they usually write to you about things like when you upload your first contacts, send your first campaign, or when you forget to put the opt-out option. Of course, they are automated emails but it happens that if you reply to one of them a real support agent will attend to your case. If you have any doubt you can write directly to support by email. I'm not sure if they are using Zendesk or any other kind of program but they usually answer in less than 2 hours. Still, the option of an actual real-time chat is missing.
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
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.
ClickSend is okay but limited in functionality as compared to HighLevel. HighLevel has more functionality and it is at a reasonable price point everyone. Apart from that support are the same for most platform and it is really great to have something that is easy to start using. Most important decision that someone have to make is what they want in these software.
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 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.
The ROI is time. More time focused, less time distracted with a mobile device.
Early days, however the customer survey and marketing campaigns will hopefully yield results.
Customer adherence to appointments and/or rescheduling for missed appointments has drastically increased with the use of reminder and follow-up SMS options that normally wouldn't be used as often on a mobile device.
