"Knock makes it easy to integrate notifications into an existing application"
4/5
What do you like best about Knock?

There are out-of-the-box UI integrations that allow for getting notifications setup quickly. The dashboard is easy to use and update the text of notifications and emails, in addition to easily modifying workflow details such as batch time and workflow steps. Customer support channels—i've used email and slack—are reliable. They get back to me within a reasonable timeframe and introduce someone else into the conversation if they are not fully knowledgable of the issue/area of focus. Review collected by and hosted on G2.com.

What do you dislike about Knock?

The out-of-the-box UI has limited customization, which prevents certain use cases from being implementable. Their support team takes requests for product improvements though! Review collected by and hosted on G2.com.

"Solves a Huge Pain Point for Platform Developers"
5/5
What do you like best about Knock?

It works like a platform developer thinks. Simple things like adding users inline, adding variables to workflows, and controlling formatting all work like you would expect. Onboarding is easy and the API is super simple to get up and running with. Beats the heck out of managing various API's for email, SMS, etc. Well worth the cost. Review collected by and hosted on G2.com.

What do you dislike about Knock?

If you just need a basic email only solution without special formatting, variables, workflow, etc. it's probably not worth the premium. Review collected by and hosted on G2.com.

"Great for handling user-specific complex workflows"
4.5/5
What do you like best about Knock?

It's super easy to use, and I'm able to run complex workflows without the need to write a ton of glue code. APIs that allow users to manage their own subscription/notification preferences is also very helpful to reducing the amount of code we have to manage. Review collected by and hosted on G2.com.

What do you dislike about Knock?

Some parts of the web dashboard is a little bit buggy. Also, since we don't use React, we can't take advantage of Knock's prebuilt in-app notification center, which is a bummer. Review collected by and hosted on G2.com.

"Knock has been extremely useful for email campaign management"
5/5
What do you like best about Knock?

The API is very clear and simple to use, and the workflow creation process is smooth and customizable. Both creating and canceling email campaigns have been very reliable for us so far. Not having to manage notification schedules with code logic or cron jobs has saved us a lot of time! Review collected by and hosted on G2.com.

What do you dislike about Knock?

The only feature I would like to see is the ability to use or import dynamic templates already existing in Sendgrid. The email template components that come with the editor are not bad, but any more advanced customization requires inserting raw HTML and CSS blocks. Review collected by and hosted on G2.com.

"Knock solved a complex problem for us and provided even more"
5/5
What do you like best about Knock?

Engineer friendly usage on all stages of implementation and integration. World class APIs to interact with it in our own way. Fast and helpful direct support. We could trust Knock so much that we built our transactional communications around their solution and we send many notifications to our users on a daily basis. Review collected by and hosted on G2.com.

What do you dislike about Knock?

Pricing was shocking first, but we could receive a startup offer with dynamic payments which solved the issue. And no matter how I calculate, implementing Knock is still much cheaper than building our own solution for this problem. Review collected by and hosted on G2.com.

"Decent Platform"
4/5
What do you like best about Knock?

Ability to easily send emails with a template and powerful features such as batching them. Review collected by and hosted on G2.com.

What do you dislike about Knock?

I had to wrap the notification preferences with an API and web-page which wasn't ideal. I was also sending badly formatted emails in outlook for a while which i wasn't aware of due to the email looking correct in the Knock dashboard. Review collected by and hosted on G2.com.

"How did I live without Knock before"
5/5
What do you like best about Knock?

Knock is one of my favourite SaaS at this moment. The unparalleled combination of simplicity and customisation is just awesome. One API call and multichannel awesomeness come to life - in-app notification goes first, later - push and e-mail for boomers. The best part is that I don't have to code anything. Business users are in full control of workflows, we review and commit to prod. What a dream! Review collected by and hosted on G2.com.

What do you dislike about Knock?

Very difficult to find any downsides to be honest. It is just a fantastic, very well thought product. Review collected by and hosted on G2.com.

"Great product with a great team"
5/5
What do you like best about Knock?

The speed of releasing new features (let alone bugs)!

I have requested several new features to the team which have all been released within a few days. Their support is great and very detailed. Review collected by and hosted on G2.com.

What do you dislike about Knock?

This isn't really their fault but they are in the US timezone so I usually have to wait a day (I am impatient) for a detailed response.

Sometimes iterating through workflows and testing them and saving to dev can be a bit of a pain. Review collected by and hosted on G2.com.

"Good platform for notifications structure"
5/5
What do you like best about Knock?

I like how I can make available flows to the entire team, so that everyone can contribute on the same notifications and workflows Review collected by and hosted on G2.com.

What do you dislike about Knock?

I would be good to have more examples of good practices about the notifications, as there may be different ways to achieve some results Review collected by and hosted on G2.com.
