MacSonik PST Viewer is a reliable software solution designed to open, view, and analyze Outlook PST files on Mac and Windows systems without requiring Microsoft Outlook installation. It helps users access mailbox data from healthy, empty, orphaned, password-protected, and minimally corrupted PST files through an easy-to-use interface.
The software allows users to preview emails, attachments, contacts, calendars, tasks, drafts, and other mailbox items before exporting them. Its advanced search and filtering options help locate specific emails by sender, recipient, subject, date range, and attachment status. Users can export mailbox data into formats such as PDF, CSV, EML, MSG, PST, and MBOX, or migrate supported data to Microsoft 365.
MacSonik PST Viewer preserves the original folder hierarchy and important email properties during processing. Additional features include duplicate email detection, attachment management, large PST file splitting, selective export, and detailed activity logs for recordkeeping and auditing. The software processes data locally, supporting greater privacy and control over mailbox information. A demo version is available to evaluate its features before purchasing a suitable license.
TenantCore is a cold email infrastructure platform for outbound operators and agencies. It is used to set up, manage and monitor the email infrastructure that cold email campaigns are sent from.
Users connect their email environments to TenantCore, add domains they own, and create mailboxes in bulk. The platform generates the required DNS records (SPF, DKIM, DMARC, MX) and can publish them automatically through supported domain registrars. Daily sending limits can be applied per mailbox at the infrastructure level, so they hold no matter which sending tool is used.
TenantCore monitors sending activity, sending reputation, sending-location changes and domain health, sends alerts when something changes, and provides reports and an API.
TenantCore is not a campaign sequencer. It works alongside sending tools such as Smartlead, Instantly and PlusVibe and manages the infrastructure underneath them.

Scribarius is an AI email assistant for Gmail, Outlook and Zoho Mail that helps professionals respond faster and stay organized, right inside the inbox they already use.
It reads each incoming email and its thread, then drafts a reply using your FAQs, documents, calendar availability and contact details. Drafts wait in the conversation for you to review and send: nothing is sent without you by default.
Key features:
- Reply drafts grounded in your own knowledge base
- Automatic follow-ups when an email gets no reply, stopping as soon as the contact answers
- Forwarding by topic, using rules written in plain language
- Smart labels by status, urgency, sentiment and topic, as native Gmail labels or Outlook categories
- Task detection with steps and deadlines, linked to the original email
- Smart templates with variables and conditions, sent now or scheduled
Scribarius integrates with Zendesk, Freshdesk, HubSpot, Pipedrive, Google Calendar and Outlook Calendar, and supports 11 languages. It is GDPR compliant, its databases are hosted in France, and the content of the emails it processes is never stored.
Plans start with a free tier. The Business plan adds a shared team workspace.
MorningZero is a unified inbox for professionals who manage several email accounts: agency owners, consultants, fractional executives and founders. Gmail, Google Workspace, Outlook, Microsoft 365, iCloud, Yahoo, Fastmail, Zoho and IMAP accounts arrive in one list behind one login.

Teams can write rules in plain English, search across every mailbox at once with Ask Zero (answers cite the source emails), and review reply drafts written in their own voice. Nothing is sent automatically.
Security: Google CASA assessed, Microsoft verified publisher. Email is never used to train AI models, and message bodies are not stored on MorningZero servers.
Available on web, macOS, Windows, Linux and Android. Plans start at $19/month with a 14-day free trial, no card required.
Autentify Verify tells you whether an email address exists and accepts mail, without sending anything. Each address goes through syntax, domain and mail server checks, and ambiguous answers get a second check. Results come with a status (deliverable, undeliverable, risky or inconclusive), a reason and a recommended action.
Three ways to use it in one account: single checks in the web app, CSV lists of up to 5,000 rows (all your columns returned, maximum cost shown before processing) and an HTTP API to validate sign-ups before saving them.
Detects catch-all domains, temporary and disposable emails and non-existent mailboxes, the causes of hard bounces and sender reputation damage.
Built for Brazilian companies: prepaid credits in Brazilian reais, no subscription, paid by Pix or credit card, with a Brazilian tax invoice (NFS-e) for every purchase. Purchased credits never expire and inconclusive results are not charged. Free credits on sign-up. LGPD compliant; Autentify does not sell data or contact lists.

Outlook Duplicate Remover is a Windows 10 and 11 program that helps you remove duplicate emails from Outlook data files without risking the mail you already have. It opens a .pst or .ost from disk, finds messages that are copies of each other in any folder, and saves the unique ones into a separate PST. The file you loaded is read and left alone.
🔰 How to use it
1. Install the app and click Add File(s) to load one PST or OST archive. Outlook does not have to run.
2. In the folder tree, tick Inbox, Sent Items, Archive and any subfolders that should be compared with each other.
3. Under Deduplication options, decide which fields must agree. Subject, Sender and Body text are ticked at first. Recipients, Date/Time sent and Attachment names make the rule stricter.
4. Set Keep as to First found, Oldest or Newest. That copy stays in each group and the others are dropped.
5. Tick the backup PST if you want the removed messages kept in a second file, and leave the CSV report on.
6. Choose a Destination folder and press Start. A message at the end tells you how many unique emails were written and how many copies were left out.
👍 Why IT and office teams pick it
- No edits to the source. Since the program only reads the archive, a wrong rule costs nothing. Change the settings and run again.
- Folder boundaries do not hide copies. Outlook's Clean Up looks at one conversation at a time, while this tool can remove duplicate emails that sit in Inbox and Archive at once.
- RE: and FW: are ignored on request, so a forwarded copy still matches its first version.
- Every run leaves a trail. The CSV lists folder, subject, sender, date and whether each message was kept or removed.
- Local processing only. Client mail is never uploaded, which matters for legal, medical and finance offices.
- The interface comes in 17 languages.
✅ Who uses it
- IT staff cleaning a user's archive after a migration or an import that ran twice.
- Office managers whose shared mailbox was set up as both POP and IMAP and now holds every message twice.
- Anyone with a slow, oversized personal archive who wants to remove duplicate emails before it reaches the size limit.
❓ FAQ
Why am I getting two copies of every email in Outlook? The same account added twice, a server that keeps its own copy in Sent, or a repeated import are the usual reasons. Fixing the cause stops new copies, and this outlook duplicate email remover cleans out the old ones.
How do I remove duplicates from a PST file? Load it, tick the folders, keep the default rules and press Start. The clean result lands in the folder you picked.
Can I remove duplicate emails using the Outlook Clean Up tool? Only inside one folder. Copies spread across folders need a file-level scan like this one.
ℹ️ Free trial: a sample of the mailbox is processed and a reminder appears, so you can judge the result on real data. A license writes the full clean copy. Windows 10 or 11, works offline.
Safilist is an email verification service that shows you exactly what was checked and why behind every result — not just a pass/fail grade.

Where other tools discard everything "risky," Safilist surfaces the addresses that are actually deliverable — so you keep leads competitors would throw away. Results export cleanly to CSV or push straight into your email platform. Built for marketers, sales teams, and developers who want cleaner lists, higher inbox placement, and verification they can actually understand. Your data is never sold, shared, or monetized — it's company policy.
