Marketing manager

The app is very friendly and easy to use, the stats are very useful, is good idea to integrated with Facebook messenger and Sirena  could work as omnichannel very soon.

Coordinator

The simple fact of having contact with the client immediately and easily is what I like the most. Integration with our Facebook is super easy and my clients are delighted.

Admin

We have been using Salesforce for a long time and our team are very experienced using CRM. When we added in the Sirena CRM, we have had great adoption by our team and our customers love the platform.

business developer

Fails in some integrations. Problems that depend on their suppliers and do not have the power to solve it.

Gerente de Marketing

Why is it so hard to be helped in this. The attendance is the worst, really.

Incredibly difficult to set up, confusing onboarding process, too many players involved in the process. Gnerally a waste of time and money.

Director 

Very useful, easy to use and a perfect way to increase my sales.

It is a perfect way to see and control all your customer service messages, get better answer times, and a more professional image to our clients.

Ingeniero Industrial

I am using it for the first month yet but things are working pretty well and I am really enjoying the better results.

Marketing Manager

It allows you to record digital sales and thus measure the effectiveness of your marketing effort. Highly recommended if you are looking to formalize communication through WhatsApp.

Coordenadora de Sucesso do Cliente

I like the idea, with few competitors and very useful.

Easy to use, easy to setup, and is a great way to admin all our customer service comunications.

Director - Partner

Bad experience, high expectations were not achieved.

Marketing

The software has an easy to use interface. And with great statistical support.

Operations Associate

The UI is intuitive and conversations are easy to manage. Creating new contacts or beginning conversations with new customers is critical to good service.

Analytics and Operations

The worst part: Searching contacts and Contacting Sirena's Support Team.

Director

The WhatsApp integration is a powerful feature to communicate with clients.

We are loving Sirenas integration with WhatsApp, since it offers a very fast channel directly to our costumers.

Followize

HubSpot CRM

The best customer service enhancement tool

It is a tool that is constantly evolving and that allows us to use its new features in order to provide the best experience to our contacts and prospects. As I mentioned previously, for us the main problem that we were able to solve was the formalization of our communication process through WhatsApp with our contacts and prospects.

Great CRM & Chat Software

No support after 20 days. No access available. Mobile and Web funcionality with erroresI can't even access with my all users. No comments...

Where is the support team?

It has been a good experience overall. We manage a lot of client's request per day, and made us more efficient in brief time. 

It makes your sales team go faster

When the client needs immediate help, just enter his WhatsApp application and send us a message and we can answer him and solve his problem immediately, without wasting time writing an email.

Magnificent work tool

Thank you  ! We are so happy to read your review. It inspires us to continue working and improving. Thank you

We are comfortable with the software.
It is very institutional, when defining changes.
Very easy training is given in compression.
Whenever we need support they are giving us a hand.

It has given us a great help in reordering our client portfolio.
Needless to say, I recommend them.


 Intuitive and easy to implement software

Thank you, Graciela ! We are so glad to read your review. It inspires us to continue working and improving. Concerning the messages that don't apply to your business, it's possible to edit them and send to Whatsapp to approve. Do you know how to do it? Please let us know how everything 's been going. Thank you!

I recommend Sirena as the best solution, at least in LatinAmerica, for managing whatsapp for sales teams.

Intuitive and value-oriented

Hi Jorge! Thank you for your review, we appreciate it. We've worked hard the past year to fix all these bugs you mention. Did you notice the difference? Let us know. Best regards.

You will probably glad to hear that Sirena is now 100% integrated with Facebook Messenger, so you will be able to answer all DM through our platform.

Luis

While sirena is amazing, very hard work must be put into its availability, this software must be HA-compliant, this cannot go down... And a better tech support is apreciated.

Excellent software, but with some quirks

¡Gracias Facundo! Siempre contamos con sus valiosos comentarios para seguir mejorando.

Sirena let us take the cliente to our different business lines without even noticing, our selling process is much faster this way.

Almost Perfect

Hi Jeronimo, Thanks for your review. We value your feedback and are thrilled you're enjoying Sirena I appreciate your comments. We're always improving our product, so I'll pass this off to the team to take this into account. 

Best, Luis

Great for little companies, with few customers and few employees.

Customer Support is to slow, very slow! Inacessible every time.

The team is spread in some places of LATAM. They need to structure their knowledge better, the salesperson told me that I could use 2 lines for 1 team, but after I signed the contract that was not able to do so. 

Easy communication software to talk to clients and prospects

Hi Samuel! Thank you for your review, we appreciate it. You left last year and since then we've improved a lot all the functionalities that you mentioned. How's it going now? Feel free to share it with us. Thank you

 We are a B2B company and this has given us a broader connection with our end customer that was formerly limited.

Wonderful tool for Inbound Marketing

Thank you! We always count on your valuable feedback to keep on improving.

the communication with clients is simple. 

It's ok but could be better

good , we need  more time to increase the usage, despite the crisis we are facing now

great tool , more to learn about it

Oh my, thank you Pablo ! We are so happy to read your review. It inspires us to continue working and improving. Thank you

Good but can improve

Bad experience, high expectations were not achieved

System unavailability

Too bad you had that experience. Every month we make more feature enhancements and fix bugs. I invite you to enter https://web.sirena.app/sign-up to become a free trial user for 7 days (without credit card) and you can try the platform!

System needs to be more fluid when changing screens. These phrases are wrecking us for having to anticipate so many different occasions.
