The CS team is very helpful. The system restricted our account and need many steps to reconnect. The CS team keeps helping through a week and the response time is very quick too. Best CS support ever :)

Having a dedicated and reliable point of contact has made a significant difference to our overall experience with SleekFlow.

Probably one of the top BSP available with many features and functions, solves most problems of a business owner would have. Although requested features are in development, its great to see that opinions are taken into heart by them. The support service is stellar as well, ensuring follow ups, updates, notices and great assistance.

I’ve been using SleekFlow for three years and have experience with both versions 1.0 and 2.0. However, I’m having difficulty transitioning from Automation to Flow Builder. Since automation is involved when creating a new contact, it now takes approximately 5–10 minutes to complete the task. I hope to gain more experience with Flow Builder and learn how to use it more efficiently. SleekFlow’s customer service team is helpful, and I can ask for assistance whenever needed. They also provide timely responses. Appreciate it!
Thank you for being with us for the past three years and for sharing your feedback throughout the transition from SleekFlow 1.0 to SleekFlow 2.0. We truly appreciate your support and insights 🙌 We understand that adapting from rule-based automation to Flow Builder can take some time, and we’re always happy to help you make the most of it. If you could share your flow with our support team, they’d be glad to collaborate with you on restructuring it for better efficiency. We’d also be happy to share relevant Flow Builder guidance and learning resources to support your journey. We’re really glad to hear our team has been responsive to your needs, and we’ll continue to be here to support you along the way 😊
Sleekflow’s functions are complete and easy to use.
Hi Michelle, we're really glad to hear you're finding SleekFlow's features both complete and easy to use — that's exactly the balance we aim for. Thanks for taking the time to share your experience! 🙌
What stood out for me is the support provided by the SleekFlow SG team. I have been through a few platforms and the importance of a support team really makes the difference. Most of my tickets/enquiries were responded within 2 hours and resolution was fast. The staff is also quite knowledgeable in the happenings from Meta as well, so information is very updated.
Hi Jovan, thank you for your feedback! It’s great to see that our support team is exceeding your expectations with their quick responses and effective resolutions. We are committed to staying ahead of Meta's updates to provide you with the most accurate guidance. We'll be sure to relay your experience to the Singapore team. Thanks again for being a SleekFlow customer!
We’ve been using SleekFlow to manage our customer messages, and so far it’s been pretty easy to use. It helps our team keep track of conversations and reply to customers without getting too messy. Whenever we’ve needed help, their support team has been friendly and quick to respond too. Overall, it’s been a good experience.
Hi Dennis, thanks for taking the time to leave this review! It's great to hear that SleekFlow has helped your team manage customer messages and stay organized. Glad our support team has been quick and friendly whenever you needed a hand too — we'll pass that along to them. Thanks again for being a SleekFlow customer!
Yong Qi is very helpful and responsible! She can always help to solve the issues. Good!
Thank you so much for the kind words, Ray! We're really glad to hear Yong Qi was able to help sort things out for you quickly. We'll be sure to pass your thanks along to her and the team. We appreciate you taking the time to share this!

Thank you for the 5-star rating, Richard! We’re pleased to know you had a great experience with AgentFlow! 🙌
Prompt & Clear Guidance: The customer service team provides direct, step-by-step instructions that make onboarding and troubleshooting completely hassle-free. Rapid Response Times: Inquiries are acknowledged almost instantly, eliminating long wait times and keeping operations moving smoothly. Proactive Follow-up: Support agents don't just close tickets—they continuously check in to ensure every issue is fully resolved and all requirements are met. Genuiely Helpful Support: The staff demonstrates deep product knowledge, turning potentially complex setup steps into a simple, efficient process. Special thanks to Yong Qi! (Super helpful Guy)
Hi Andy, thank you so much for the detailed and thoughtful review! It really means a lot to hear that the step-by-step guidance made onboarding and troubleshooting hassle-free, and that our team's proactive follow-ups gave you the confidence that things were actually resolved, not just closed out. We'll be passing your shoutout along to Yong Qi directly, she'll be genuinely delighted to read this. Thanks again for choosing SleekFlow, Andy.
We’ve had a very positive experience with SleekFlow. It has helped our team keep customer conversations organized and made our day-to-day communication much more efficient. The platform is straightforward to use, and overall it has been reliable for our needs. We especially appreciate being able to manage conversations in one place, which makes it easier for the team to stay aligned and respond to customers smoothly. So far, SleekFlow has been a useful addition to our workflow, and we’re very happy with the experience. Definitely a platform we’d recommend to other businesses looking to improve their customer communication.
Thank you so much, Beethoven! It's great to hear that SleekFlow has helped keep your team's conversations organized and made day-to-day communication so much smoother. We especially love that having everything in one place has made it easier for your team to stay aligned and respond to customers quickly – that's exactly what we hope SleekFlow can do. Thanks again for the kind words and for recommending us to other businesses. It means a lot to the team! 🙌
I really like the Flow Builder as a social media manager. Made running giveaway campaign and product drops really easy as I can just automate reply and DM. Works like Manychat but the feature is free for trial.
Hi Jenny, thank you so much for your lovely review! Giveaways and product drops are exactly when replies and DMs pile up faster than one person can keep up with, so it's good to know Flow Builder is handling that rush while you run the campaign itself. Thanks again for taking the time to share your thoughts with us! 🙌
SleekFlow has been a huge help for our team. From assisting with Meta approval to providing technical support during setup, the entire process was smooth and well supported. The platform is easy to use and has made our WhatsApp mass messaging campaigns much more efficient. What stands out the most, though, is the quality of their customer support—quick, friendly, and always willing to help. We're very satisfied with the experience and would definitely recommend SleekFlow to other businesses.
Hi Tiago, Thank you for sharing your experience with SleekFlow. We're delighted to hear that you've had a positive experience with both our platform and team. We truly appreciate your trust, support, and recommendation. We look forward to continuing to support your success.
Highly recommend Derrick! He was incredibly patient and professional throughout the entire process of setting up. Despite multiple meetings to fine tune the system, he was always supportive and dedicated. Thank you, Derrick, for going above and beyond! 🙌
Hi Toby, Thank you for the kind words. We're glad Derrick made the setup process a smooth and supportive one — we'll be sure to pass your feedback along to him. 🙌 We look forward to being part of your continued success.
I’ve had a very positive experience with SleekFlow so far. There are three main areas where they really stand out: Exceptional Support: The team is incredibly responsive. Whenever I have a concern or a specific inquiry, they are right there to help me navigate it, which gives me a lot of confidence in the platform. User-Friendly Interface: The UI is clean and intuitive. It didn't take long for me to get comfortable with the layout, making my daily workflow much smoother. Easy Automation: Setting up automation flows can often be a headache, but SleekFlow makes it quite easy to handle. It’s straightforward to build out logic that actually works for my needs without needing a deep technical background. Overall, it's a solid tool that has definitely simplified our communication processes!
It is honestly unbelievable that such a terrible program even exists. Sending templates is a nightmare — you have to search for the country prefix by the domestic country name, which makes absolutely no sense and wastes time. Customer support is practically non-existent. It takes them days to respond, and when they do, the answers are often completely off-topic and unhelpful. On top of all that, pricing is extremely non-transparent and ends up being much higher than advertised. They have promissed me i WILL have an onboarding. Never happened. I have been promissed to be able to connect with make.com. Not possible. I have been promissed I will have carrousel image template messages. Also not possible... Lying scam company, asked money up front and then simply disapeared. Overall, this is one of the most frustrating and disappointing software experiences I’ve had. Avoid. Edit: they turn off messaging service in the middle of the sunday before previous warning…
