Comparison

Onmindo vs Mixmax, written by the people who built Onmindo

This comparison is written by Onmindo, about Onmindo and Mixmax, so read it with that in mind. The parts where Mixmax is better are as easy to find here as the parts where Onmindo is. If you are a sales team of fifteen with Salesforce, stop reading and buy Mixmax. If you are one to three people who want to know what happened to an email without renting a sales platform, keep going. If you are not yet sure Mixmax is the thing you are replacing, start with the three categories a Mixmax alternative can mean.

Onmindo vs Mixmax, in one paragraph

Mixmax is a mature sales engagement platform: sequences, CRM sync, team analytics, scheduling, dialer, the lot, priced per seat for organisations that need all of it. Onmindo is a small tool that does the five things individuals actually use from that category, sends every message through your own Gmail account with the least Gmail permission each job needs, names which recipient opened, and costs nothing today. Different products for different buyers, with an overlap in the middle where most solo users live.

01

Their side

Where Mixmax is better

Not a courtesy section. These are real reasons to choose them.

  • Mixmax is mature, and Onmindo is new

    Mixmax has been in production for years with a large customer base, a support organisation, and the operational scar tissue that comes with both. Onmindo is new. That matters more than any feature row on this page.

  • Mixmax has team features, Onmindo has none

    Shared templates, team analytics, round-robin routing, roles, SSO. Onmindo has none of them and is not going to: it is built for one to three people who each send from their own account.

  • Mixmax syncs with a CRM, Onmindo does not

    CRM sync with Salesforce and HubSpot, calendar and meeting scheduling, a dialer. If your workflow runs through a CRM, Onmindo will not fit it, and is not trying to.

  • Mixmax runs sequences across a team

    Mixmax sequences run across a team's whole pipeline, with CRM steps and reporting. Onmindo's sequences are multi-step follow-ups for one sender, paced by its own deliverability caps. A campaign engine they are not.

  • Mixmax has a support desk, Onmindo has one person

    A hosted vendor with a support team is a real thing to buy. Onmindo's support is one person answering email.

02

Our side

Where Onmindo wins

  • Your mail leaves from your own Gmail account, and Onmindo asks for the least permission that job needs

    Onmindo does not relay mail. The extension asks the server to mint a pixel token, injects it, and hands the message back to Gmail to send, so authentication is Google's and the sending reputation is the one your address already has.

    • Send, and your address. That is the whole of what connecting Gmail asks for, and that token cannot read mail.
    • Read access is asked for per feature. Telling a reply from an out of office needs the thread, so Onmindo asks then. Decline it and the rest still works.
    • Naming which recipient opened needs the full Gmail permission, because Gmail's submission server accepts no narrower one. It stays off until you switch it on.
    • Mixmax asks for full mailbox access up front, because sending through Gmail's SMTP needs it.

  • Opens mean opens, and they have names

    Gmail fetches your pixel twice, and only one of those fetches is a reader. Once the moment it delivers the message, before anyone has looked at it, and once more for each person who opens it.

    • Onmindo knows the delivery fetch by its signature and files it as delivered, not opened. What is left is a person.
    • Switch the group send on and a message to several people leaves as one copy each, so the hover card names who opened, when, and in what. That one needs the full Gmail permission and is off until you ask for it. How Onmindo tracks several recipients.
    • For a Gmail reader there is no device and no city, because Google's proxy did the fetching. Mixmax prints "Mountain View, California" there, which is where that proxy lives.

  • Onmindo is free today, and Mixmax is priced per seat

    Onmindo charges nothing at the moment, and publishes its intended prices anyway: Free at 200 tracked sends a month, Pro at $9 a month or $84 a year, per account rather than per seat. Mixmax's paid plans, on its own pricing page on 4 September 2026, run from $29 to $89 per user a month billed annually. For two people using a fifth of the product, that is about $170 a year against about $700, and today it is nothing against about $700.

  • Onmindo reports nothing from inside your inbox, and blocks the library that would

    The part of Onmindo that runs in Gmail measures nothing and is built with no analytics code in it. Onmindo counts usage on its own dashboard and settings screens, where there is no mail to see. Onmindo also uses InboxSDK for Gmail DOM compatibility, and that SDK reports usage to its author including a hash of your Gmail address, so the extension ships a network rule that blocks it.

  • Deliverability guardrails that refuse, not just warn

    Four rules, and each of them refuses rather than warns. Click tracking is off by default and blocked for bulk sends on a tracking domain under fourteen days old. The daily cap ramps from twenty, by twenty a day. Pacing is jittered, thirty to a hundred and eighty seconds. A bulk send with no visible opt-out is blocked outright.

  • Follow-ups survive an out of office

    Onmindo classifies the inbound message before cancelling anything, so an autoresponder does not silently end your sequence. Only a genuine human reply stands the follow-up down.

04

The decision

Who should pick Onmindo, and who should pick Mixmax

Pick Mixmax if

You run a sales team, your pipeline lives in a CRM, you need sequences today, you need shared templates and team reporting, or you want a vendor with a support desk and no server of your own.

Pick Onmindo if

You are one person or a small team, you want to know what happened to the emails you already send and which person it happened to, you want the tool to hold the least access to your mailbox it can, you care that the open count is honest, or you simply refuse to pay seat pricing for a fifth of a platform.

Pick neither if

You want certainty about who read your email. Nobody can sell you that, and the ones who imply it are the ones to be careful with.

05

Migration

Migrating from Mixmax

There is no importer. Here is the honest path, about half an hour.

  1. Copy your templates across by hand

    Copy them across by hand. Onmindo templates are a name, a subject and a body, and variables use {{first_name}} style placeholders, so rename yours as you paste. There is no bulk import and building one for a handful of templates would take longer than the pasting.

  2. Move your do-not-contact list first

    If you keep a do-not-contact list, add those addresses in the dashboard's Suppressions page with reason "manual" before your first send. This is the one step worth not skipping.

  3. Tracking history does not move

    Opens and clicks recorded by another tool stay with that tool. Onmindo starts counting from your first tracked send.

  4. Run them side by side for a week, but not on the same message

    Two extensions both intercepting a Gmail send is a bad time. Track a message with one or the other, then compare what each one told you. That week also shows you which of your old "opens" were Gmail's delivery-time prefetch: Onmindo lists those as delivered, not opened.

  5. Warm up before you switch bulk work over

    A new tracking domain starts cold, so click tracking is blocked for bulk sends for about two weeks and the daily cap starts at twenty and ramps. Stand the instance up early, let the domain age while you are still on the old tool, and the switch costs you nothing.

  6. Cancel after your sequences drain

    If you have live Mixmax sequences, let them finish. Onmindo has sequences but no importer, so recreate the ones you still need.
