01At a glance

What is Zoho CPaaS?

Zoho CPaaS (communications platform as a service) is Zoho’s service for transactional messages: the receipts, reminders, alerts and codes your systems send to one person at a time. It started as ZeptoMail, an email delivery service, and in 2026 added WhatsApp, voice calls and SMS behind the same console and credentials.

Newsletters and promotions belong in Zoho Campaigns; Zoho CPaaS does not allow marketing email.

02What we hear

Five messaging headaches Zoho CPaaS was made for

Most teams that call us already send notifications. The trouble is what nobody can see afterwards. Tap a card to see what changes with Zoho CPaaS set up properly.

03Inside Zoho CPaaS

Zoho CPaaS features, channel by channel

Each channel has its own setup and rules. Around them sit Agents, templates, webhooks and one analytics view.

  • Transactional email

    Send by REST API or SMTP relay. Opens, clicks, bounces and spam complaints come back as events, and high-volume senders can add a dedicated IP.

  • Automated voice calls

    Outbound calls read a message and branch on keypad answers, built in a drag-and-connect call-flow editor. Calls go out from local numbers you buy and verify in the console.

  • SMS

    Zoho added an SMS API too, but availability depends on your Zoho data center; we confirm for your account on the discovery call. Need US texting today? Our Twilio SMS and Zoho integration is the other path.

  • Agents, templates and one report

    An Agent is a separate sending stream with its own credentials, suppression list and numbers. Give orders, reminders and test traffic one each and a staging mistake never reaches a customer. Analytics filters results by channel, date or Agent.

04One build, six pieces

How we build appointment reminders on Zoho CPaaS

A sample build for a Southern California clinic group: WhatsApp reminders first, email as the backup. Scroll, and each step adds its piece to the console.

  1. Step 1Domain

    The sending domain proves who it is

    We add the DKIM and CNAME records Zoho CPaaS asks for to your DNS, so reminders leave from your own name and pass checks at the inbox.

  2. Step 2Agent

    Reminders get a stream of their own

    A dedicated Agent keeps reminder traffic, keys and suppressions apart from receipts and test sends.

  3. Step 3Templates

    The WhatsApp wording goes to Meta first

    A Utility template with name and time variables goes to Meta for approval, plus an email version for anyone not on WhatsApp.

  4. Step 4Consent

    Permission lives on the contact

    Opt-in, source and date become Zoho CRM fields filled by your intake form. Your counsel approves the wording; we make sure it is stored.

  5. Step 5Trigger

    The CRM decides when and which channel

    A scheduled workflow runs a Deluge function a day before the visit. It reads the consent fields and calls the Zoho CPaaS API for WhatsApp or email.

  6. Step 6Logs

    Front desk sees who actually got it

    Delivered, read and undelivered events come back by webhook and land on the contact; staff call the few it never reached.

Sample clinic, domain and wording. Keep health details out of the message itself; your counsel decides what a reminder may say.

05What we do

Zoho CPaaS services from our Los Angeles team

Six kinds of work come up on Zoho CPaaS projects; the BRD lists which ones you need.

Account, domains and channels ready to send

We confirm your channels, verify domains, connect the WhatsApp Business Account and buy and verify voice numbers.

  • DKIM and CNAME records on every sending domain
  • Agents per product, team or environment

06Try it · sample send

What happens when the first Zoho CPaaS message doesn’t get through?

Webhooks tell you a message was delivered, read or undelivered. A small rule can then try the next channel. Pick a message, a first channel and a backup, then run it.

07Who uses it

Which US businesses get the most from Zoho CPaaS?

08Zoho CPaaS vs separate APIs

Zoho CPaaS vs Twilio, SendGrid and Mailgun style setups

If your customer data lives in Zoho, one Zoho service for email, WhatsApp and calls is simpler to run. For US texting at scale or marketing email from the same tool, a separate vendor still has the edge.

Messages on Zoho CRM records Native email view on CRM and Bigin records; other statuses written back by webhook.A connector or custom code per vendor.
Logins, invoices and admins One Zoho account and console for every channel.One account and bill per vendor.
SMS to US numbers Depends on your Zoho data center; we check yours.A core product for dedicated SMS vendors.
Marketing email from the same tool Not allowed; use Zoho Campaigns.Some email APIs also offer marketing sends.
WhatsApp templates Utility and Authentication templates, approved by Meta.Also built on Meta’s approval process.
Paying for quiet months Prepaid credits, no monthly fee, every feature from day one.Varies: some plans carry monthly minimums or tiers.
Track record on new channels WhatsApp and voice are new and still marked beta.Longer history running these channels.

Where another tool fits: if texting is the heart of your process, keep a dedicated SMS provider and connect it to Zoho. That is what our Twilio and Zoho integration does, and it can run alongside Zoho CPaaS email.

09Zoho CPaaS pricing in the US

How much does Zoho CPaaS cost?

There is no subscription. You buy credits for the channels you use. One email credit is $2.50 and sends 10,000 emails within six months, and the first credit is free. WhatsApp and voice draw down prepaid balances at per-message and per-minute rates.

Channels you plan to use

From 500 to 1,000,000 a month. Credits last six months, so the estimate covers a six-month block.

Your six-month estimate List prices, USD

    Zoho CPaaS list prices in USD before taxes. Email and WhatsApp credits expire six months after purchase; voice credits don’t expire. Zoho offers custom pricing to very high-volume senders, and we check current rates for your data center before you buy. Our setup work is billed separately, as a fixed price in a signed BRD that names every message stream.

    Zoho CPaaS questions from US teams

    Quick answers on channels, pricing and consent. Bring the rest to the first call, which is free.

    Book a discovery callEstimate your usage →

    What is Zoho CPaaS?

    Zoho CPaaS is Zoho’s communications platform for transactional messages. It sends email by API or SMTP, WhatsApp Business templates and automated voice calls from one console, with SMS where your data center supports it.

    Is Zoho CPaaS the same as ZeptoMail?

    Yes. ZeptoMail was renamed Zoho CPaaS when Zoho added WhatsApp, voice and SMS. Existing email setups carry over unchanged.

    Can a US account send SMS through Zoho CPaaS?

    SMS availability depends on your Zoho data center, and we confirm it for your account on the discovery call. If it isn’t available to you yet, we connect Twilio to Zoho for texting and use Zoho CPaaS for email, WhatsApp and calls.

    How much does Zoho CPaaS cost?

    Email is $2.50 per credit of 10,000 emails, valid for six months, and the first credit is free. WhatsApp is Meta’s per-message rate for the destination country plus a 10% platform fee. Voice uses $1 credits that never expire, with a 10-credit minimum and Zoho Voice rates for numbers and minutes. There is no monthly fee.

    Does Zoho CPaaS work with Zoho CRM?

    Yes. Transactional emails show on Zoho CRM leads and contacts, and Zoho Flow can send email or react to email events. For WhatsApp and calls, we write a Deluge function that calls the API and a webhook receiver that saves each status to the record.

    Can we send one-time passcodes with Zoho CPaaS?

    Yes. WhatsApp Authentication templates and automated voice calls both suit codes. Your app or a Zoho function creates and checks the code; Zoho CPaaS delivers it.

    How do you handle TCPA and CAN-SPAM consent?

    We don’t give legal advice. Your counsel sets the rules; we store opt-in status, source, date and channel as Zoho CRM fields and make every send check them first.

    How long does a Zoho CPaaS setup take?

    It depends on how many streams and channels you need, and Meta’s template review adds time for WhatsApp. The signed BRD dates each stream and test, so go-live is known up front.

    12How a Zoho CPaaS project starts

    Every message stream gets named before the first API key

    Four steps settle what we build and what it costs. One email stream is often scoped on the first call; several channels plus a migration may need a paid scoping phase, quoted up front.

    We run these projects online across the US, Canada and Latin America, and meet Southern California teams in person when that helps.
