Mailbutler alternatives for Mac

The best Mailbutler alternative depends on which Mailbutler feature you used. If it was the AI, Alrighty is the pick on a Mac with iCloud, Gmail or Outlook: it writes replies in your own voice from what you sent that person before, and lets the AI you already use, such as Claude or ChatGPT, work in your mail. Alrighty has no read tracking, templates or send later, though. For those, Spark, Superhuman and Canary Mail are Mac mail apps with tracking and scheduling built in, and Boomerang adds them to Gmail in your browser.

Most Mailbutler alternative lists are made by tracking tools, and they name Gmail extensions that don't run in Apple Mail. None of them sorts the picks by the Mailbutler feature you'd be replacing, or says which company gets your mail once you switch. This page does both.

How we checked

We read each vendor's own product, pricing and privacy pages on November 4, 2026. Every fact about another product links to its source, and where a page didn't say something, we say so. For each app, we noted which Mailbutler features it replaces (read tracking, templates, send later and AI writing), what it costs, which accounts it works with, and where your mail goes. We did not test the apps. Alrighty is our app, and it's listed first.

What Mailbutler does, and why people switch

Mailbutler is "an extension that adds powerful email productivity tools to your Apple Mail, Gmail, or Outlook inbox" (Mailbutler). Its pricing page lists open and click tracking, message templates, mail merge, notes, tasks, signatures, and a Smart Assistant that composes messages, summarizes them and drafts replies with AI (pricing).

Price. Per user, per month, Starter is $5, Professional $9, Smart $14 and Business $32. Billed yearly, they are $4, $7, $11 and $24. Mailbutler says "Start with a free 14-day trial that includes all features. No credit card information required." Our Apple Mail plugins guide says which plan carries the AI and how to install it on macOS 27.

Where your mail goes. Mailbutler says "our servers are located in Frankfurt, Germany," and "We never read, analyze, or store your messages’ content or attachments. We only transmit your email body to OpenAI when you use the Smart Assistant feature. Email addresses are replaced with dummy variables."

People leave Mailbutler for a few reasons we can tie to its pages:

• It's a subscription per user, and the AI sits on the higher plans.
• It's an add-on. It adds to Apple Mail, Gmail or Outlook. It doesn't change what lands in your inbox.
• It needs its own account, with its own servers, next to your mail provider.

Alrighty: best if you used Mailbutler for its AI

Alrighty is a mail app for Mac, Windows and Linux that puts iCloud, Gmail and Outlook accounts in one inbox. It isn't an add-on, so you leave Apple Mail, Gmail's website or Outlook to use it. It belongs on this page for Mailbutler users who came for the Smart Assistant, and for those who want their inbox fixed, not only their outbox.

• Suggested replies in your voice. Signed in, opening a reply starts a draft written from what you sent that person before. It reads up to 12 of your sent emails for your voice and up to 12 messages of the conversation. Ask for a change in your own words, such as "say yes to Friday," or click Shorten, Warmer or Formalize. It's always a draft, and you send it. Our AI email writer guide compares it with Mailbutler's kind of AI and others.
• Your own AI. A local MCP server lets Claude, ChatGPT's desktop app, Codex, Cursor or a local model read and search your mail. It's off until you turn it on with Connect AI. That AI can also work in a window you watch: open mail, write replies, file messages. Nothing sends until you click Send.
• Ask your mail. Ask a question and get the answer, with the emails it came from. Search runs on your Mac and matches meaning as well as words.
• Stop mail. One action ends a sender's mail: it unsubscribes, archives their mail, and moves new mail from them out as it arrives. Clean up lists the senders you likely don't want so you can stop them all at once.

What it doesn't replace. Alrighty has no read tracking, no templates, no send later and no mail merge. It has no notes, tasks or CRM links either. If you send sales mail and need to know who opened it, keep Mailbutler or pick one of the apps below.

Price. A 14-day trial with no card, then a Free plan or Pro. Free has a small monthly AI allowance.

Where your mail goes. Your mail stays with iCloud, Google or Microsoft, and Alrighty keeps its copy and search index on your Mac. Your passwords and sign-ins stay on your Mac, encrypted with a key from your system's keychain. Its AI features send only the emails they need to Alrighty's server, which asks a model: OpenAI's for answers and replies. Clean up sends each sender's address and up to 3 of their newest emails to the server to sort them. Signed out, nothing goes to Alrighty's server. No ads, on any plan.

What it can't do. There's no iPhone or web app, so it can't follow you to your phone or a browser. It takes iCloud, Gmail and Outlook accounts only, not Yahoo, AOL, Fastmail or other IMAP. It has no calendar, and it's new, with no long track record. See everything Alrighty does.

Pick it if you used Mailbutler to write and answer mail with AI, and you'd rather have that in a Mac app that also stops the mail you don't want.

Spark: best for tracking, templates and send later on every device

Spark is a mail app for Mac, iPhone, Windows and Android from Readdle. Its pricing page lists Scheduled Sends and Reminders among its essentials, Custom Templates on Plus, and Read Statuses on Pro (pricing). Its feature pages also name Send Later, Snooze and Gatekeeper (Spark).

AI. Spark +AI writes, translates, summarizes and drafts on the paid plans. Spark says its AI runs on "the Azure OpenAI Service," which "does not use this data to train models" (Spark).

Price. Free, then Plus at $10 a month or $99 a year, and Pro at $20 a month or $199 a year. Read Statuses are on Pro.

Where your mail goes. Spark says some features "require our server-side email processing to work," and it stores your login for IMAP, AOL and Exchange accounts, encrypted (privacy).

What it can't do. Read Statuses cost $199 a year, more than Mailbutler's Starter plan. It's a full mail app, so you leave Apple Mail. Our Spark alternatives page covers its servers in more depth.

Pick it if you want Mailbutler's sending tools built into one app on every device you own.

Superhuman: best for read statuses on Gmail and Microsoft 365

Superhuman is a mail app for Gmail and Microsoft 365, "Built for teams that use Gmail or Outlook" (Superhuman). It lists Read Statuses, Send Later, Snippets, Remind Me and follow-up reminders (plans). "In Superhuman Mail, you can see when people read your email and on which device."

AI. Superhuman AI writes, replies, summarizes and labels. The Business plan adds Auto Drafts, Ask AI and an MCP server.

Price. Starter is $25 per member a month and Business $33, both billed annually. Each plan bundles Mail, Grammarly, Docs and Go.

Where your mail goes. Superhuman's pages disagree. A blog post says your inbox "is stored on your machine," while its privacy policy says it receives "emails and drafts" you let its products access (privacy).

What it can't do. It takes Gmail and Microsoft 365 accounts only, so no iCloud or Yahoo. It doesn't run inside Apple Mail. Its lowest plan is $25 a month, billed yearly, against $4 for Mailbutler's Starter billed yearly. Our Superhuman alternatives page has more.

Pick it if you work in Gmail or Microsoft 365, send a lot of mail, and want to see who read it.

Canary Mail: best for read receipts and templates on a free plan

Canary Mail is a mail app for Mac, iPhone, iPad, Windows and Android. Its free plan includes "Read Receipts (Lite)" and "Email Templates," and Growth adds full Read Receipts, Send Later and AI Copilot (pricing).

AI. AI Copilot writes, replies and summarizes on Growth and up. Canary's privacy policy names "top-tier providers such as OpenAI, Anthropic, Cohere, Google and others" (privacy).

Price. Free, then Growth at $36 a year and Pro+ at $100 a year. Canary has "no monthly subscriptions," so you pay yearly or once for a lifetime license.

Where your mail goes. Canary says account details are "stored on your device and is never transferred to our servers," except for push notifications, when it will "temporarily store your email address, credentials, sender, subject line" (privacy).

What it can't do. Send Later and full read receipts need Growth. The free plan covers up to 2 devices. Our Canary Mail alternatives page covers the rest.

Pick it if you want tracking, templates and send later for the lowest yearly price, on every device.

Boomerang: best for send later and tracking in Gmail's website

Boomerang is a browser extension for Gmail, "For Firefox 38+, Chrome 5.0+, Safari 5.1+, Opera 15+, and Edge 39+," and it "Works with Gmail and Google Workspace email" (Boomerang). There's also an add-in for Office 365 and Outlook.com (Boomerang for Outlook). Its Gmail plans list Send Later, reminders, response tracking, read receipts, click tracking and Respondable, an AI that helps you write "better, more actionable emails."

Price. The free Basic plan gives 10 message credits a month. Personal is $4.98 a month, Pro $14.98 and Premium $49.98, all billed annually. New accounts get "a Free 30-day Trial of Boomerang Professional," and "Credit card information is not required" (pricing). That pricing page shows a 2017 copyright, so check the price in the app.

Where your mail goes. The pages we read don't say what Boomerang stores or where.

What it can't do. It doesn't work in Apple Mail or a Mac mail app. You use Gmail in a browser, or Outlook. The pages we read don't describe templates.

Pick it if you already work in Gmail's website and want send later and read receipts for the least money.

What Apple Mail does without an add-on

If you used Mailbutler for reminders, Apple Mail may already do enough. "If you send a message and don't receive a response in 3 days, the sent email automatically resurfaces to the top of your inbox to help you remember to follow up" (Apple). You turn it on or off with Follow Up Suggestions in Mail > Settings > General. Apple Mail has no read tracking of its own. Our Apple Mail alternatives page covers what else it lacks.

Can I use Claude or ChatGPT instead of Mailbutler's AI?
