...
With a 5-star rating from over 750 reviews, Knock prides itself on building a better bridge between homes.
...
We considered using knock given the current market conditions.
...
Knock sells your information many times.
...
Knock repeatedly and severely mismanaged the closing of my house, eventually forcing the buyer to cancel the purchase agreement.
...
So if you want to work with incompetent liars, Knock is the company for you.
...
I even questioned Knock on the “missing of the closing date” issue and was assured that processes have improved.
Well, Knock missed one closing date and looks like they’re about to miss another one !!
...
We are now 2 days past the 2nd scheduled closing date and I haven’t received an update from Knock.
...
The concept of Knock is great but the execution of the concept was terrible in my experience.
...
after submitting the earnest money and paying for the inspections and appraisal ( knock requires you pay that upfront out of pocket).
...
However, this was only an option for me because I was told Knock allows you to recast your loan terms after the sale of your home and 60 days has passed.2) I would be able to take our profit from that sale and apply it the principal and get my monthly payment and equity to a comfortable range...seemed like a great plan from Knock.
...
I was told that never happens and they would not be selling my loan before I could recast ...7 days later I received a notice from another bank welcoming me as a client since they had just purchased my loan form Knock!
...
We decided to try Knock as the concept of buying without a downpayment was appealing.
...
Knock Lending waited until the day before closing to request the documents needed.
...
Knock Lending had access to the condominum association budget since early in the process and they were unable to notify us of the fact that reserves were low and we would have to give a 25% downpayment.
...
The last straw was when our title company's lawyer reached out to us to warn us that knock was attempting to put a lien on the property we were selling, which would have meant us losing our cash buyer.
...
In summary, please avoid knock, they are untruthful and disorganized, and you may lose your home as well as the future property you are contemplating buying.
...
When we thought it was over, the night before we were going to close on our house a knock rep.
...
knock never apologized or expressed remorse for their unprofessionalism and lack of diligence not only for this instance but through out the entire processes.

At this point, I think Knock just doesn’t want to do business!

**Vendor:** Knock
...
- Users find the **missing features** of Knock, including replay capabilities and problematic email templates, frustrating.
...
- Users find the **insufficient features** in Knock to be limiting, particularly with email templates and documentation clarity.
...
I like that Knock is super robust and easy to use.
...
Setting it up wasn't that bad—I've dealt with similar systems before that were much tougher, but Knock made it pretty easy.
...
We encountered some limitations with user preferences regarding commercial unsubscribe, and it would be beneficial to have a Knock preferences UI that we can direct people to from an email to help manage compliance.
...
The only major downside to Knock is that the filtering and pagination in some of the observability views in the Knock dashboard can feel a bit limiting.

Working with knock has been a complete disaster for my family.
...
It’s become a part of my morning routine to wake and see what Knock needs today.
...
We don’t have anywhere near that much money in reserves and Knock knows this.
...
Our credit card utilization has actually decreased since we joined knock, and our loan advisor reassured me that our price decrease of our house would not be a problem.
...
Our realtor has called and left numerous messages for updates throughout this process because she too was concearned about how late Knock was asking for certain documents.
...
She ended up sending the title and contract to 3 different people, due to the lack of professionalism on knocks behalf.
...
After taking a couple days away from knock, my realtor tried to reaching out to try to fix all of this and move forward.
...
We just had to keep reaching out to Knock constantly.
...
Now they are asking us to start the process with Knock all over as if it’s day 1.
Working with knock has been the worst decision of my life.
...

...
The bridge loan option with Knock allowed us during the peak of a hot Seller market to get the house we wanted before selling our existing home.
...
I've closed a number of loans with them and helped clients who were in tricky situations get out of them and get into a new home with not only my help, but with help of the great people over at Knock as well.

## 19 Best Knock Alternatives
...
Not a notification router like Knock, but purpose-built for SaaS email marketing.
While Knock handles notification infrastructure across channels, Sequenzy focuses on making email work for SaaS - AI generates complete onboarding, conversion, and retention sequences from a product description, and Stripe integration automatically syncs subscription events to trigger the right emails.
If you're using Knock mainly for email notifications and marketing, Sequenzy does that specific job better and at a fraction of the cost.
...
Best Knock alternative for teams wanting open-source.
Novu mirrors Knock's multi-channel approach - email, push, SMS, in-app, and chat - but lets you run the entire stack on your own infrastructure if you want.
The in-app notification center component is the closest open-source equivalent to Knock's notification bell.
Cloud pricing starts at $30/month after a free tier, which is dramatically cheaper than Knock's $250 jump.
...
The trade-off is that it's less polished than Knock's commercial offering, and self-hosting requires real DevOps effort to run reliably in production.
...
Multi-channel like Knock but with stronger marketing automation.
...
Where Knock is notification infrastructure (send this message through these channels), Customer.io is behavioral marketing automation (when this user does X, trigger Y across channels with personalization).
...
At $100/month for 5k profiles, it's cheaper than Knock's paid tier while offering significantly more marketing capability.
...
Unlike Knock, there's no in-app notification feed component, so if your product needs a notification bell, look elsewhere.
...
Not multi-channel like Knock, but best developer experience for email.
...
If you're using Knock primarily for email notifications (password resets, receipts, alerts), Resend does that specific job with a much better developer experience.
At $20/month for 50k emails, it's dramatically cheaper than Knock's $250 tier.
...
Less feature-rich than Knock.
...
However, it's push-only - no email, SMS, in-app notifications, or the kind of multi-channel orchestration that Knock provides.
...
Unlike Knock's $250 pricing jump, SuprSend offers more gradual scaling with usage-based pricing after a free tier.
...
Fyno stands out with its breadth of channel support - beyond the standard email/push/SMS that Knock covers, it handles WhatsApp, RCS, IVR, and regional messaging platforms through a single unified API.
...
More marketing-focused than Knock but handles notifications too.
...
Not multi-channel like Knock, but handles email volume that Knock's email channel can't match.
...
More email-focused than Knock but with behavioral targeting that Knock's email channel lacks.
...

Knock, similar to Iterable, offers comprehensive cross-channel messaging capabilities across email, SMS, push, chat, and in-app notifications.
However, Knock emphasizes a strong developer-first approach with extensive tooling like SDKs and CLI, designed for deep integration into development workflows, while also providing an intuitive drag-and-drop editor.
