Nitrosend vs Zepic.

Email-first, agent-native, unlimited contacts, and one bill with no channel add-ons.

TL;DR

Zepic is a customer engagement platform with a real CDP under it. Email, WhatsApp, and Instagram DMs run against one customer record, sold to D2C brands and ecommerce retailers, and Zenie AI is the voice-driven copilot that builds journeys, segments, and campaigns from a prompt. If WhatsApp or Instagram is where your program actually lives, that bundle is the argument and it's a good one.

Nitrosend specializes in email, so the comparison is only interesting on two axes: what the email half costs, and who drives the software. The comparison index has the rest of the field if the multichannel bundle isn't the requirement. Zenie drives Zepic from its dashboard, so an agent gets whatever that dashboard already puts in front of a person. Here every capability is an email API endpoint and an MCP tool before it's a screen, contacts are unlimited on every plan including Free, and BYO sending keys on Pro and above keep the transport where you want it.

Pricing math

What you actually pay.

Zepic bills a platform fee set by the contacts you hold, then each channel is an add-on on top of that fee, and WhatsApp conversation charges sit on top again. We bill the mail you send and leave contacts unlimited. So read these rows on the total, not on the platform line.

Migration

How to switch (or run both).

Zepic keeps sending while you move, and if your WhatsApp and Instagram programs run there, those stay exactly where they are.

Add and verify your sending domain in Nitrosend. DKIM and SPF records sit alongside Zepic's, so both platforms can send from the same domain for as long as the overlap lasts.
Export your contacts and their attributes from Zepic and import them with nitro_import_contacts. Zepic custom objects hold more than a contact record does, so decide which attributes travel and which stay behind with the CDP.
Start with one low-stakes message type, a receipt or a password reset, sent with nitro_send_message. Watch it for a week before a campaign follows it.
Rebuild Zepic journeys as flows with nitro_compose_flow. The triggers have equivalents on both sides: contact added, attribute changed, and event fired. Store events can arrive over the API from the same source that fed Zepic.
Decide what carries your reputation. BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, and Zepic's own pool isn't one of them, so a sender leaving it is warming a new path whichever platform it lands on. What travels with you is the domain and its authentication history.

Honest credit

What Zepic does well.

Picking a tool is about fit. Here's what Zepic is genuinely good at.

A real CDP under the marketing tools rather than a contact list wearing the label: multiple custom objects, custom data mapping, custom data sync, transformation, and filtering.
Anonymous visitor tracking and cookie-based contact tracking, so a session that never signs in still builds a profile.
The WebSDK is one line of JavaScript and it captures visits, events, and form submissions.
WhatsApp is a first-class product rather than a bolt-on: broadcast, chatbot, automation, carousels, smart retries, and authentication templates each have their own surface.
Instagram DM automation is a shipped channel, including comment-to-DM funnels.
Team Inbox turns a broadcast into a two-way conversation, and it's included from the entry plan up.
Zenie AI takes plain English or a spoken prompt and builds journeys, segments, custom objects, and campaign content.
Around two dozen named integrations across ecommerce, CRM, support, loyalty, POS, billing, and logistics, with inbound and outbound webhooks behind them.
Native INR pricing rather than a converted number, which matters to the market the product was built around.

What Nitrosend adds

Where we think we're better.

Contacts are unlimited on every plan, including Free, so a list that grows without being mailed never moves the bill.
Zepic's platform fee is set by the contacts you hold and ours by the mail you send, which is where a big list mailed in segments diverges hardest.
One bill, and no channel is an add-on switched on over a platform fee.
Email is the product here rather than a line item, so the roadmap isn't shared with a CDP, a chatbot, and an inbox.
A published price from 500,000 to over 4,000,000 emails a month, where the ladder usually turns into a sales call.
MCP-first is an architecture, not an integration: every capability is an API endpoint and an MCP tool before it's a screen.
Zenie is a copilot inside Zepic's dashboard, so the agent surface there stops where the screen does.
The difference shows at the edges: deliverability, billing, tests, and approvals are tools here, and they're the four that usually stop an automation dead.
BYO sending keys on Pro and above route your mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, on the domain and IP you already warmed.
BYO keys make the move reversible, and switching platforms otherwise means switching sending reputation on the same day, when the two failures look identical.

Use case fit

When to pick which.

Pick Zepic if

WhatsApp or Instagram is where your customers actually reply, and you want those conversations on the same record as the email program. It points the same way if you run a Shopify or WooCommerce store and want browsing, cart, and order data unified in a CDP that counts anonymous visitors too, or if you want a copilot that builds a journey from a spoken prompt. None of those are close calls.

Pick Nitrosend if

Email is the channel your program runs on and you'd rather have one product than a platform fee plus three add-ons. It's the right call too when your database is much larger than your monthly send and you're tired of paying for addresses you don't mail, or when you want the platform to answer to an agent end to end, including the deliverability, billing, test, and approval steps that usually send someone back to a dashboard. Shortlists that start with a suite tend to also weigh Zoho Campaigns, ActiveCampaign, and ActiveTrail.

Zepic vs Nitrosend - common questions.

Can Nitrosend replace Zepic?

For the email half, yes. Campaigns, flows, segments, templates, contacts, and transactional sending are all here on one bill, with contacts unlimited on every plan. Zepic keeps the channels it was built for, so a team whose program runs on WhatsApp or Instagram DMs either keeps Zepic for those or splits the stack deliberately. Nitrosend specializes in email, and that's the half this page compares.

Is Nitrosend cheaper than Zepic?

It depends on which number is bigger, your list or your monthly send, and on how many channels you switch on. Zepic charges a platform fee set by the contacts you hold, then each channel as an add-on, then WhatsApp conversations on top of both. We charge the send and leave contacts unlimited. The entry rungs sit close together at $20 against $23, and the highest rung with a published price is $300 against $179.

Does Zepic have an MCP server?

Not one it publishes. Zenie AI is a copilot inside the Zepic dashboard, driven by a typed or spoken prompt, so an agent reaches the product through whatever a connector chooses to expose on top of it. Nitrosend was built the other way round: the endpoint and the MCP tool come first, and the screen is built on top of them. Build order is what decides whether an agent reaches every capability or only the parts that already have a screen.

What happens to my WhatsApp and Instagram programs if I switch?

They stay on Zepic. The WhatsApp Business number is bound to a business account with Zepic's messaging provider, and the Instagram DM automations sit in the same place, so neither one moves when the email program does. Nitrosend specializes in email, so the email half comes across on its own schedule while those channels keep running. Your sending domain authenticates with SPF, DKIM, and DMARC for both platforms for as long as the overlap lasts.
