Is there a free email tracker for Gmail?

Yes. The HawkOpen Free plan costs €0 with no time limit and works in Gmail through the browser extension: opens are tracked without a limit, each with a classification, and link clicks in 10 emails a month.

Checked: November 12, 2026

The Free plan includes 1 mailbox and 7 days of history. Emails sent on it with a chosen look (a mail design) carry a short HawkOpen line in the footer, and every tracked email ends with a short notice about tracking. After the monthly link limit, opens are still tracked but links are left untracked.

Each open is labelled, for example as likely human activity or as a mail-provider proxy such as Apple Mail Privacy Protection, because an open alone does not prove reading. The extension also works in Outlook on the web and Yahoo Mail, in Chrome and Firefox.

Where rules that require consent apply, tracking may start only after that consent has been obtained. The link in the message lets the recipient withdraw consent later.

Is it cheaper to pay for HawkOpen yearly or monthly?
Yearly is cheaper. Pro costs €48 a year or €6 a month, and Business costs €90 a year or €11 a month, all plus VAT.
Can I use the HawkOpen CRM on the Free plan?
Yes, as a paid add-on. It starts with a 21-day trial for up to 1,000 contacts; a card is needed to start. Then it costs €3 a month or €30 a year plus VAT, for up to 5,000 contacts, and you can cancel at any time. Pro and Business include the CRM.
What are HawkOpen prices in US dollars?
In US dollars Pro costs $6 a month or $48 a year, and Business costs $11 a month or $90 a year. These prices are before tax.
How does the HawkOpen Intro offer work?
You pay €1 plus VAT and get full Business access for the first 20 days. From day 21, Business continues with yearly billing at €90 a year plus VAT and renews every year until canceled. You can choose monthly billing at €11/month instead. If you cancel during Intro, it does not renew.
How many mailboxes can I connect on each HawkOpen plan?
Free: 1 mailbox. Pro: 3 mailboxes. Business: as many as you need. A plan belongs to one user, so one person can track several of their own addresses within the limit.
How do I cancel my HawkOpen subscription?
In the HawkOpen dashboard, open your plan and choose to cancel, or open the billing portal from there. Cancellation takes effect at the end of the period you already paid for; until then you keep your plan.
Do I have a 14-day right to withdraw from a HawkOpen purchase in the EU or the UK?
Whether you can withdraw from the contract or get a refund depends on your status as a customer, the law that applies and the terms of your contract. If the law or your contract gives you that right, you can use the procedure described in your purchase confirmation and the withdrawal function in HawkOpen. Cancelling the renewal of a subscription is a separate step.
Can I get a refund from HawkOpen, for example if I cancel a yearly plan mid-year?
Usually not. HawkOpen gives no voluntary refunds once a paid period has started, except where mandatory law or a withdrawal right requires otherwise. If you cancel a yearly plan mid-year, it simply does not renew, and you keep it until the end of the year you paid for.
Who do I contact about a billing problem with HawkOpen?
For your card and renewal, open “Manage billing” on the Pricing page of the HawkOpen dashboard, which takes you to the billing portal run by Stripe. For anything else, contact us through the HawkOpen app; a contact form on hawkopen.com is coming soon.
Do consumers and businesses buy HawkOpen on different terms?
The plans and prices are the same for everyone. A business can enter its VAT ID in the HawkOpen panel before buying, and every consumer has a 14-day right of withdrawal.
Can I pay for HawkOpen in euros or in US dollars?
Yes. Pro and Business can be bought in euros, the default, or in US dollars, with the same numbers. Both are net prices: the VAT of your country is added to euro prices, and any tax for your billing address to dollar prices. HawkOpen Intro is sold in euros only.
Where can I update my card or manage the renewal of my HawkOpen plan?
Open the Pricing page in the HawkOpen dashboard and choose “Manage billing”. It opens the billing portal run by Stripe, HawkOpen’s payment provider, where your subscription and payment details are handled.
Which company and VAT number appear on HawkOpen invoices, and can I change my details?
The seller is TriStiX S.L., a company in Spain; its VAT ID is listed on the Terms / Imprint page of hawkopen.com. Your name and billing address come from what you enter at checkout, and your VAT ID from the HawkOpen panel, where it is checked in VIES before the purchase.
How does the VAT reverse charge work for EU companies, and where do I enter my VAT ID?
Enter your VAT ID in the HawkOpen panel before you buy. HawkOpen checks it in the EU VIES register; only a valid number is passed to Stripe, so you pay the net price right away and account for the VAT in your own country under the reverse charge.
Do HawkOpen’s euro prices include VAT?
No. Prices in euros are net. A consumer in the EU pays the VAT of their country on top: the pricing section of the home page shows the net price and the price with VAT for your country and its rate, and checkout shows the total with the VAT of your billing address before you pay.
What happens if my HawkOpen payment fails or is disputed?
Paid features stop and your account uses the Free plan until the payment is sorted out. Your account is not deleted, and changing to Free does not delete your tracking data.
Can I try HawkOpen’s paid features without a credit card?
No. HawkOpen has no free trial of Pro or Business. The Free plan needs no card, while HawkOpen Intro is a paid start of €1 plus VAT and always requires a payment method.
Do I get invoices for my HawkOpen subscription, and where do I find them?
Payments are billed through Stripe, HawkOpen’s payment provider, not in the HawkOpen dashboard itself. To see your billing details, open “Manage billing” on the Pricing page, which takes you to Stripe’s billing portal.
Which payment methods does HawkOpen accept, and can I pay by bank transfer or purchase order?
You pay on Stripe’s checkout page with one of the methods Stripe offers for your country and currency, such as a card. HawkOpen does not offer payment against an invoice, purchase orders or a bank transfer after an invoice.
Who processes HawkOpen payments, and does HawkOpen store my card details?
Stripe processes the payments. You type your card details on Stripe’s checkout page, not on a HawkOpen page, and HawkOpen keeps only a reference to your Stripe customer and subscription, not your card number.
Will the price of my HawkOpen subscription change later?
HawkOpen has not published a rule about future price changes or notice periods. The current price list, with net prices, was approved on 12 November 2026. Subscriptions bought at an earlier price keep it; nothing moves them to the new list automatically.
Does HawkOpen offer discounts for students, non-profits, agencies or resellers?
No. HawkOpen has no student, non-profit, agency or reseller pricing, and the checkout does not accept promotion codes. The only discounts are the lower yearly price and a volume discount for teams.
Can I switch between Pro and Business, or from monthly to yearly billing?
Not by yourself yet. HawkOpen has no self-service switch: the billing portal offers no plan changes, and a new purchase is not possible while a subscription is running. You cancel, and when the paid period ends you buy the plan or period you want.
Do US customers buy HawkOpen from a US company?
No. All customers, including those in the United States, buy from TriStiX S.L., the company in Spain that runs HawkOpen. There is no US company.
Does HawkOpen charge US sales tax?
Dollar prices are shown before tax. At checkout, Stripe Tax calculates any tax that applies to your billing address, and you see the amount before you pay.
Is SaaS taxable in my US state?
It depends on your state’s rules, and HawkOpen does not give tax advice or describe each state. When you buy HawkOpen in US dollars, the checkout calculates any tax that applies to your billing address.
What happens to my HawkOpen account and history after I cancel, and can I come back later?
You keep your plan until the end of the paid period; then the account moves to the Free plan and is not deleted. Free shows only the last 7 days of history, but older data is not erased by the plan change, so it shows again if you subscribe again while it is still kept.
Can HawkOpen Intro turn into a yearly plan instead of a monthly one?
Yes. When you start Intro you choose whether it turns into Business monthly or Business yearly (€90 a year plus VAT). During Intro you can still change it to Pro monthly, Pro yearly or Business monthly, but Business yearly can only be chosen at the start.
Is there a HawkOpen Enterprise plan with custom terms?
No. HawkOpen sells only Free, Intro, Pro and Business, on the same published terms for everyone; larger teams buy Pro or Business with one seat per person and get a volume discount.
How many PDF links and signature requests do I get on each HawkOpen plan?
Free gives 5 PDF links and 1 signature request a month, Pro 10 PDF links and 5 signature requests, and Business has no limit. All of these are a preview until external malware scanning of files is switched on.
Why does the HawkOpen Free plan add a line to my email footer?
It is how the Free plan is paid for: on Free, an email sent with a chosen look (a mail design) ends with a short line, “Sent with HawkOpen”, in the language of that look, with a link to the site. A plain email without a look gets no such line, and Pro and Business never add it.
What are the differences between HawkOpen Free, Pro and Business?
Free tracks opens without a limit and links in 10 emails a month, for 1 mailbox. Pro adds 3 mailboxes, 365 days of history, unlimited link tracking, scheduled sends, reminders, reply detection and the CRM with up to 25,000 contacts, and Business adds polls, reports, webhooks, unlimited mailboxes and up to 250,000 CRM contacts. Every plan, Free included, has the address book with recipient lists and campaigns: up to 50 recipients per campaign on Free and 500 on Pro and Business.
What does the HawkOpen Business plan include?
Everything in Pro, plus polls, a larger CRM (up to 250,000 contacts), weekly and monthly reports, webhooks, email and Microsoft Teams alerts, and no limit on mailboxes. It costs €90 a year (€7.50 a month, 31% less than paying monthly) or €11 a month, plus VAT.
What does the HawkOpen Pro plan include?
Pro (€48 a year (€4 a month, 33% less than paying monthly) or €6 a month, plus VAT) gives you 3 mailboxes, 365 days of history and link tracking without a monthly limit, plus scheduled sends, reminders, reply detection and the CRM with up to 25,000 contacts. Emails carry no HawkOpen footer line.
Does HawkOpen have hidden limits or fair-use rules?
The limits that differ by plan are the ones on the pricing page: mailboxes, history, link-tracked emails on Free, templates, PDF links, signature requests and campaign recipients. HawkOpen publishes no other usage caps by plan.
When do HawkOpen monthly limits reset?
On the first day of each calendar month at midnight in the time zone set in your settings, or at 00:00 UTC if none is set. The counters are kept per user, not per mailbox.
How long is my tracking history kept on each HawkOpen plan?
The plan sets how far back you can see: 7 days on Free, 365 days on Pro and no plan limit on Business. Separately, tracking data is deleted after your workspace’s retention period, 365 days by default.
Who can use the HawkOpen Intro offer, and how often?
Intro can be used once per customer account, workspace and payment method, and a verified company tax ID also allows only one Intro. It is not available if you already have a HawkOpen subscription.
How many opens and link clicks can I track on the HawkOpen Free plan?
Opens are tracked without a limit, each with a classification. Link clicks are tracked in 10 emails a month. Either way, only recipients with a recorded consent are tracked, once your company has switched tracking on.
Which HawkOpen plan is right for a freelancer, a sales team or a company?
Free suits you if you only want to see opens and some link clicks from one mailbox. Pro suits a freelancer or salesperson with several addresses who needs reminders, reply detection, the CRM and a year of history; Business suits teams that need polls, reports, webhooks or more than 25,000 CRM contacts.
How do I see which HawkOpen plan I am on?
Open the Pricing page in the HawkOpen dashboard: your current plan is marked there, and during Intro you also see when it ends.
