As answered by people managing GitHub Codespaces and Zixflow.
Zixflow's answer:
Choose Zixflow if your customers are on channels they reply to, like WhatsApp and RCS, and delivery matters to your business.
Zixflow may not be the right fit if you only use email. A dedicated email tool will likely serve you better.
Zixflow's answer:
Zixflow is built for consumer brands whose customers are on channels that reply, like WhatsApp and RCS.
The main audiences are:
Within these companies, Zixflow is used by:
Zixflow's answer:
Zixflow started with a problem we kept seeing: businesses were losing customers in the gaps between their messaging tools, and nobody could see it.
A signup didn't go through because the OTP arrived late. A campaign reported 100,000 messages "sent" but reached far fewer people. A customer replied asking "COD available?" at 9 PM and never heard back.
None of this showed up as a failure on any dashboard, because each tool only reported its own part.
So we built Zixflow to run the whole journey in one place: verify the customer, reach them on the channel that works, answer every reply, and learn from every result. It runs on our own delivery infrastructure, so we can report what was actually delivered.
Today, Zixflow has delivered over 2 billion messages for more than 1,000 brands, including banks, consumer apps and D2C brands.
Zixflow's answer:
Zixflow's answer:
Most businesses run customer messaging on three separate tools, and each one has a gap.
Messaging APIs send OTPs and alerts, but when an SMS fails, the customer is simply gone. Marketing tools send the same message to everyone and report "sent", not "delivered". Engagement tools were built before customers could reply, so when someone replies on WhatsApp, nobody answers.
Zixflow handles the full loop in one platform:
Zixflow also runs on its own delivery infrastructure, and reports what was actually delivered, not just what was sent.
