Postmark vs. SendBird vs. Twilio

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.

SendBird is well suited tool for those who are having sound technical knowledge and in-hand experience of app development and APIs. One might find it difficult to integrate if not having a technical team or a good technical background. Once implemented, using or management is not an issue. Startups having low budget might find it a little bit costier.

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.

• Great, helpful customer support (rarely needed)
• Reliable product
• Well thought out interface, easy setup
• Great ongoing visibility into status of emails sent through Postmark

• Moderation around comments & chats.
• SendBird UIKit was super helpful for the design team.
• Our devs raved about the API documentation being so thorough & easy to follow.

• 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.

• Not many cons since it's pretty straightforward, and if email delivery service was often impacted, we'd most likely find a new provider.

• It's support system is not that efficient
• Documentation needs improvement
• It's pricing is a little bit high comparing to other available options

• 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.

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.

The developer APIs and SDKs are super easy to follow.

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.

Being in South Africa, direct local currency support would be nice

• Using SendBird has decreased the number of support calls to where we were able to hold off on increasing our customer support team's headcount.
• Customers have raved about having the chat functionality to review & assess their healthcare options without having to call in.
