9 Best Email Tracking Software of 2026

HubSpot treats email tracking as part of Sales Hub rather than a separate add-on, and the tracking itself is free. Reps send tracked emails from Gmail, Google Workspace, Outlook, Office 365 or inside HubSpot, and get a notification when a lead opens a message, clicks a link or downloads a document. Notifications can arrive in Sales Hub, the browser, the desktop or a third-party CRM. The bigger difference from a standalone tracker is where the data goes: each open and click is associated with the contact record in the HubSpot Smart CRM, so the next rep to pick up the account sees the full history. Paid editions add email sequences that follow up automatically and predictive lead scoring. Starter lists at $20 per seat per month, with a limited-time $10 offer for new customers, and Professional starts at $100 per seat. Reps who only want read receipts may find HubSpot heavier than a Gmail extension, but for teams that want tracking tied to a CRM it is the strongest free option.

Mailbutler is an inbox extension that covers Apple Mail, Gmail and Outlook, which makes it one of the few trackers for reps who work in Apple Mail. Every plan includes basic tracking, which shows when an email was first opened and a link first clicked, with real-time notifications on desktop and mobile. The Smart plan, at $11 per user per month billed yearly or $14 monthly, is where it becomes a sales tracker: it keeps a full history of opens and clicks, shows device and location, tracks each recipient separately on group emails, and sorts tracked emails into high, medium and low urgency for follow-up, with an AI assistant that drafts the reply. Business at $24 billed yearly adds a custom tracking subdomain, IP blacklisting so coworkers' opens are ignored, and a sync of tracking events to a CRM. Starter at $4 is cheap but limited to first opens. The 14-day trial includes every feature and needs no card.

Yesware is one of the few trackers built for both Gmail and Outlook, with a Chrome extension for Gmail and an add-on for Outlook. The Free Forever plan covers basic open and attachment tracking, but its tracking views are limited to emails sent less than 24 hours ago, so it works more as a trial than a daily tool. Pro, at $15 per seat per month billed annually or $19 monthly, unlocks unlimited open, link and attachment tracking plus a personal activity report and a recipient engagement report. Premium at $35 removes Yesware branding and adds unlimited campaigns, shared templates and team reporting. Enterprise at $65 is aimed at Salesforce shops, with an inbox sidebar and sync of sent emails, replies and calendar events. Campaign limits on Pro are tight at 20 recipients a month, so reps who run outbound sequences will need Premium. For reps who mainly want to know who opened, clicked and viewed attachments, Pro is a fair price.

Mailtrack is the plain read-receipt tracker of this list: install the extension and Gmail shows double-check marks on sent messages once they are opened. Mailtrack is now part of Mailsuite, which also sells an Outlook add-in and a Gmail add-on for iOS and Android. Every plan, including Free, tracks unlimited emails, but the plans differ on history: Free shows only the first open, the paid Mailtrack plan keeps the last 7 days and the Mailsuite plan keeps the full history. Link click tracking is limited to 10 emails on the two lower plans and unlimited on Mailsuite, which also adds hot-conversation alerts, custom alerts, group-email open details and mass email up to 60k emails a month. Paid plans are priced per user per month, but the pricing page showed only euro prices to our checker, so we mark the price as pending. For a rep who wants to see whether a single email was read, the free plan is enough; for click tracking at volume, the top plan is required.

Mixmax combines email tracking with outreach automation inside Gmail. Every paid plan tracks opens, clicks and replies on every email without a cap, sets follow-up reminders at send time and logs each send and reply to your CRM, with integrations for Salesforce, HubSpot, Slack and Zapier. Pricing is based on how many people you add to sequences each month rather than on features: 50 recipients is free with limited features, 100 costs $29 per user per month billed yearly, 1,500 costs $89 and 3,000 costs $129. All paid plans include every feature, including booking pages, AI meeting notes and templates, and the 14-day trial needs no credit card. Custom tracking domains and branding are a $9 per member add-on, which matters for deliverability on tracked links. Reps who only need read receipts will pay more here than with a dedicated tracker, but teams that want tracking to drive automated follow-up get both in one Gmail tool.

Streak is a CRM that lives inside Gmail, and its email tracking is part of a free set of email power tools that also includes snippets, mail merge of 50 emails a day and a thread splitter. Tracking shows when an email is read and when links are opened. The paid plans are about pipeline management: Pro, at $49 per user per month billed annually or $59 monthly, adds shared pipelines with unlimited records, custom fields, automatic email sharing for every deal and contact, contact enrichment and 20 AI credits a month. Magic fields fill in data such as last reply and time in stage, which turns tracking signals into pipeline columns. Pro+ at $69 billed annually adds automations, integrations and advanced reports. Streak only runs in Gmail and Google Workspace, so Outlook users should look elsewhere. Reps who want tracking alone can stay on the free tools, while teams that want deals and email history in one window get more value from Pro.

Boomerang started as a send-later tool for Gmail and still centers on follow-up rather than analytics. Its response tracking brings a message back to your inbox if nobody replies by a date you choose, which for many salespeople matters more than knowing about an open. The plan table also lists read receipts and click tracking, plus meeting scheduling with Meeting Poll, bookable schedules and suggested times written into one email. The free Basic plan allows 10 message credits a month, and new accounts get a 30-day trial of Boomerang Professional without a credit card. Personal costs $4.98 per month billed annually but supports only Gmail accounts, so anyone on Google Workspace needs Pro at $14.98. Premium at $49.98 is the top tier, and the plan table lists Salesforce and CRM integration among its features. Boomerang does not work in Outlook through this product, and its tracking reports are lighter than Yesware's or Mailbutler's.

Right Inbox is a Gmail extension that bundles tracking with the scheduling tools salespeople use daily. The free Limited plan is for solo use and covers send later, reminders and recurring emails for 5 emails a month, but it does not include email tracking, mail merge, sequences or CRM integration. Professional, at $7.95 per user per month billed yearly or $9.95 monthly, makes every feature unlimited: email tracking, mail merge, sequences, CRM integration, recurring emails, reminders, private notes and templates. The Team plan at $16.95 billed yearly covers unlimited team members and adds priority support. The extension works in Chrome, Safari and Firefox. Right Inbox publishes less detail on its tracking than Mailbutler or Yesware, such as whether it reports per-recipient opens, so reps who need detailed engagement data should compare carefully. For a Gmail user who wants tracking, recurring emails and simple sequences in one inexpensive extension, Professional is a sensible middle option.

Mailmeteor is a mail merge tool first, and email tracking comes with every plan, including the free Hobby plan. That makes it a fit for reps who send the same personalized message to a list of prospects from Gmail or a spreadsheet and want opens and clicks for each recipient. Hobby allows 500 emails a month with a daily limit of 50 and three campaigns. Starter, at $5.99 per user per month on monthly billing, raises the limit to 5,000 emails a month and adds reply detection, email verification, shared templates and branding removal. Premium at $17.99 adds automatic follow-ups, email warmup, a custom tracking domain and bounce detection, and Professional at $35.99 adds inbox rotation and CRM integration. Mailmeteor works from Gmail, Google Sheets, Google Docs and an Excel add-in. It is less suited to tracking individual sales threads than Yesware or Mailtrack, but for batch outreach with tracking it is inexpensive.
