How we grade them
| 2.4GPAMailbutlerFair | 2.0GPARight InboxFair | |
|---|---|---|
| Value for money | CPaid Starter is $4 a user a month billed yearly, but its feature list is the same as the free plan's. Templates, mail merge and assignments need Professional at $7, and the AI needs the $11 plan, so you're at or above this category's $8 middle. Business is $24. | CProfessional is $7.95 a month billed yearly, which is the middle of what email tools charge. |
| Free plan and trial | CStarter is free for good, with first-open and first-click tracking, notifications and signatures. But every email you send carries a visible Mailbutler watermark. The 14-day trial of all features needs no card. | CFree is solo use, with send later, reminders, tracking and templates capped at 5 emails a month. You will hit that in a week. |
| Features | CAs an add-on it does its job: open and link tracking, templates with placeholders, mail merge from contacts or a CSV, notes and tasks on emails, assignments in a shared inbox and automations. That's a smaller job than a mail app's, and the AI, full open history and CRM sync are rationed by plan. | CSend later, reminders, tracking, sequences, mail merge and CRM sync. Gmail only, so it's a Gmail add-on rather than a mail app. |
| Ease of use | BNo rating on record, and little to set up: it adds itself to the mail app you already use and tracking starts working, with no new inbox to learn. The iPhone and Android apps are companions that need a desktop install first. | CNo store rating on record, though the page cites 12,000+ Chrome store reviews. You install an extension and learn its tools. |
| Platforms and integrations | BInside Apple Mail, Gmail in Chrome, Safari or Edge, and Outlook, on Mac and Windows, with companion phone apps rather than standalone ones and no web app of its own. It connects to HubSpot, Salesforce, Asana, Todoist, Trello and Evernote, and custom SMTP is still coming soon. | CA Chrome, Safari or Firefox extension for Gmail, with CRM integrations. No phone app, and nothing outside Gmail. |
| Best for | tracking and templates inside the mail app you have | send later and tracking inside Gmail |

Worth knowing
Mailbutler
- It is an add-on, not a mail client: it runs inside Apple Mail, Gmail in Chrome, Safari or Edge, and Outlook. The iOS and Android apps are companions that need a desktop install.
- The free Starter plan puts a visible Mailbutler watermark on sent emails and covers only basic tracking and signatures.
- The AI Smart Assistant, per-recipient tracking and full open history need the Smart plan at $11 per user / month, billed yearly.
- HubSpot and Salesforce tracking sync, a custom tracking subdomain and IP exclusion are limited to Business. Custom SMTP is listed as coming soon.
Right Inbox
- It works only with Gmail, as an extension for Chrome, Safari or Firefox.
- The free plan allows 5 emails a month for most features, so regular use needs a paid plan.
- The pricing page does not show the yearly total, and its monthly and yearly labels sit behind a toggle.
- The page says Team has unlimited team members but does not say whether its price is per seat.
Key features
Mailbutler
- Email tracking
- Shows when a message was first opened and its links first clicked, with real-time notifications. Full open history, device and location details and per-recipient tracking start at the Smart plan.
- Templates and mail merge
- Message templates with placeholders, and mail merge that fills them from Apple, Google or Outlook contacts, HubSpot, Salesforce or a CSV file. Both start at the Professional plan.

- Rules made of a trigger, optional conditions and actions can tag emails, add notes or tasks and apply signatures when a draft is created, an email is sent or opened, or a link is clicked.
- Smart Assistant
- The AI assistant drafts emails and replies from a few keywords, corrects and rephrases drafts, summarizes messages and finds to-dos in them. It is part of the Smart and Business plans.
- Email signatures
- Signature templates, custom HTML signatures, call-to-action buttons and team sharing are on every plan. UTM link personalization and dynamic content need Business.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
