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.
Grasshopper is well suited for basic needs of texting in and out as well as calling out if you would like to avoid using your personal line. It also eliminates the need to have a dedicated land land in your office or business. You can obtain a vanity number and forward calls through grasshopper.
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.
It would be nice to have the ability to transfer some calls to another Grasshopper IVR, for those customers who mistakenly dial the wrong number (we have two incoming numbers, one for corporate and one for sales).
Likewise, it would be nice to have the ability to forward to a toll-free number, which would have allowed us to work around the inability to transfer between IVRs (see above).
Lastly, it would be great to have an 'emergency' switch setting (default off but could be toggled on) that would let us override all IVR settings and transfer all incoming calls elsewhere (either to a direct dial or toll free number) for those rare times when we cannot take any calls (such as a weather emergency OR the one time each year we take all of our staff on a retreat) - that would allow us to send all calls to a backup answering service rather than just voicemail.
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.
When I was setting up my account I contacted support a couple of times. They were also very professional, personable, and helpful. Their response is prompt and thorough. I'm confident I can get any question answered as well as help with any issue I might have. That's pretty important to me.
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.
I have not used any other phone services like Grasshopper. I know that there is another option out there called Ruby, which is more like a virtual receptionist but since I did not try it out I cannot compare the two. When I started my company I found the services that Grasshopper offers to be perfect. It still works for us and we have no need to change to anything else right now.
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.
