Advanced Read Receipts on every email you send
Never on our servers
Your mail goes straight from your provider to your devices
AI that stays in the office
Drafts and summaries made on your own computer
Works with Gmail, Google Workspace, Yahoo, iCloud and your company’s own mail server (IMAP)
Advanced Read Receipts
Stop guessing. Know your email was opened.
Every email you send shows when it was opened and how many times, with an alert the moment it happens. No add-ins, nothing for your client to click, and honest results: automatic opens by Gmail and Apple Mail are marked so you are never misled.
Invoices
Be sure your invoice was delivered and opened. When a payment is late, you know whether to resend it or simply send a friendly reminder, and you can say “I saw you opened it” with confidence.
Proposals and quotes
Call when your proposal is fresh in their mind. Several opens in one afternoon usually means it is being discussed: the perfect moment to follow up.
Contracts and documents
Know the contract, the price list or the onboarding pack reached the right person before the deadline, not after it.
Marketing and announcements
Send a personal copy to each client with mail merge and see who opened it. Follow up with the people who are interested and stop guessing what works.
Productivity
Win back hours every week.
The routine parts of email, done for you. Set them up once and NotiSpark keeps working in the background.
Mail merge
Send one personalized email to hundreds of clients, each with their own name and details, from your own address.
Quick Steps
File, reply, forward and tag in one click. Turn the things you do ten times a day into a single button.
Sweep rules
Keep the inbox clean automatically: move, archive or delete newsletters and notifications by sender.
Scheduled send
Write tonight and have it delivered at 9 the next morning, when your client is at their desk.
Automatic replies
Out of office, holidays or after hours: a polite reply goes out for you.
Smart Inbox
Clients and priority mail first; newsletters and notifications folded into cards you clear in one click.
Private AI assistant
Reply drafts, summaries of long threads and a morning briefing, made on your own computer.
Snooze and follow-ups
Bring an email back when you need it, and get a reminder when nobody replies.
Security and privacy
Client confidentiality, built in.
Lawyers, accountants, clinics and agencies handle information that must stay private. NotiSpark is designed so we never need to see your email.
AI that never leaves the computer
Client emails are not sent to us or to an AI company. The built-in AI runs on your own machine.
Passwords locked to the device
Email passwords are kept in the operating system’s secure storage, and backups are encrypted.
End-to-end encrypted sync
Signatures, rules and contacts are encrypted on your device before they sync. We cannot read them.
Phishing and lookalike warnings
NotiSpark warns you about senders pretending to be a bank, a supplier or a brand you trust.
Respectful read receipts
Your recipients’ email addresses stay on your devices, we never store their IP addresses, and read-receipt records are deleted after 12 months.

Questions
Questions from businesses
Is NotiSpark a good email app for a small business?
Yes. NotiSpark is built for owners, freelancers and small teams: Advanced Read Receipts for invoices and proposals, mail merge, Quick Steps, scheduled send, automatic replies and a private AI assistant, on Windows, Linux and Android.
How do I know a client opened my invoice or proposal?
With Advanced Read Receipts on, every email you send shows when it was opened and how many times, and you can get an alert the moment it happens. Your client does not need to click or install anything.
Can I use NotiSpark for email marketing?
For personal, one-to-one style campaigns, yes: mail merge sends each client their own copy from your address, and Advanced Read Receipts show who opened it. Only email people who agreed to hear from you and include a way to opt out. For very large newsletters, a dedicated newsletter service is still the better tool.
Is NotiSpark suitable for confidential client information?
Your email goes directly from your provider to your devices and never through our servers, and the built-in AI runs on your own computer. That makes NotiSpark a good fit for lawyers, accountants, clinics and agencies. Check your own professional rules as well.
Should I tell clients I use read receipts?
It is good practice, and in some countries, especially in Europe, it is expected. A line in your email signature or privacy notice, such as “We use read receipts to make sure our emails arrive”, is usually enough.
Does it work with Microsoft 365?
Sign in with Microsoft for Microsoft 365 work accounts is coming soon. Today NotiSpark works with Gmail, Google Workspace, Yahoo, iCloud and any company mail server that offers IMAP.
Can I try the Business plan first?
Yes. New accounts get every Business feature free for the trial period, with no card needed. After that, keep using the free plan or choose Business.
Can I set up NotiSpark for my whole team at once?
Yes. In your account, Team setup lets you choose the company email server, a shared signature filled in with each person’s details, rules, tags and safety settings once. When people sign in, the app sets itself up, and each person only types their own email password, which never comes to us. IT can also install NotiSpark on every Windows computer quietly with the MSI package.
