Đọc hiểu rõ hơn về chức năng # AutoSPAM vs Gmail and Outlook's Built-in Spam Filters Written by [Adam Petras](https://bots4.me/about-us/), Founder & CEO, TreeLab OÜ · Published 2026-10-29 · Updated 2026-10-29 What the built-in filters do well, where business mail still gets lost, and what a second layer adds, as of October 2026 Gmail and Microsoft 365 both filter spam before it reaches you, and for many mailboxes that is enough. The trouble starts when a real order or a supplier's reply ends up in Spam or Junk, or when the inbox is technically spam-free but still full of newsletters, notifications and strangers. **AutoSPAM** is a spam filter for your company mailbox that works on top of the provider's filter: it sorts what arrives, rescues known senders from Junk and learns from the folders you drop emails into. It does not send email to anyone but you. This page explains, neutrally, what the built-in filters do according to Google's and Microsoft's documentation as of October 2026, and when AutoSPAM is worth adding. 🤖 The bot in this comparison AutoSPAM - Spam Filter for Your Company Mailbox First month free · No card needed [🚀 Start your free Discovery month](https://bots4.me/bots/) [AutoSPAM product page](https://bots4.me/product/autospam/) ## 🛡️ What the Built-in Filters Do (as of October 2026) Both large providers filter incoming mail on their servers before it reaches any mail app. They are good at recognising mass spam and many malicious messages. Here is what their own documentation says about how business users and admins control them. ### Gmail and Google Workspace - **Automatic spam detection:** Gmail flags suspicious messages and places them in the Spam folder. - **User controls:** *Report spam* moves a message to Spam; *Not spam* moves it back. According to Google, after you remove an email from Spam, future emails from that sender won't go to Spam, and adding a sender to Google Contacts also stops their messages from going there. Filters can label or mark messages from specific senders, and blocked senders keep landing in Spam. - **Admin controls in Google Workspace:** admins can define approved senders lists whose messages bypass Gmail spam filters, let internal messages bypass the filters, send spam to a quarantine for review instead of the user's Spam folder, and turn on more aggressive filtering, which Google warns will mark more incoming messages as spam. ### Outlook and Microsoft 365 - **Anti-spam on the server:** every Microsoft 365 organization with cloud mailboxes includes anti-spam protection. The anti-spam policy decides whether a message classified as spam is delivered to the Junk Email folder or held in quarantine, and zero-hour auto purge can move an already delivered message to Junk when it is later identified as spam or phishing. - **User controls:** each mailbox has a Safe Senders list, a Safe Recipients list and a Blocked Senders list, which users manage in Outlook or Outlook on the web and admins can manage for them. Microsoft notes that Safe Senders entries are inputs to filtering, not the final verdict: malware and high-confidence phishing detections take precedence. - **Limits to know:** Microsoft documents a synchronisation limit of 1,024 entries for Safe Senders, Safe Recipients and trusted contacts together. It also recommends leaving the Outlook desktop Junk Email Filter at "No automatic filtering" in Microsoft 365, so that the client does not conflict with the server's verdicts. ## 📉 Where Business Mail Still Gets Lost The built-in filters answer one question for every message: spam or not spam. That works for most private mailboxes. Business mailboxes run into a few recurring problems that are not failures of the filter so much as limits of that single question: - **A real order in Junk.** A first-time customer, an unusual attachment or a message from a shared sending service can be classified as spam. If nobody checks Junk that day, the order waits, and a message held in quarantine first has to be released. - **A "clean" inbox that is still full.** Newsletters, shop promotions, social notifications, read receipts and cold emails from strangers are not spam in the technical sense, so they stay in the inbox next to customer orders. - **Training in many places.** Each user teaches their own mailbox. A company with several mailboxes, or with mailboxes on different providers, repeats the same blocking and allowing in each one. ## 🤖 What AutoSPAM Adds on Top 🛡️ Provider filters spam → 🤖 AutoSPAM sorts the rest → 📂 You move one email → 🧠 AutoSPAM learns the sender AutoSPAM connects to your mailbox and works inside it, after the provider's filter has done its job. It reads every new message, decides what it is and moves it into a clearly named _AutoSPAM folder, or leaves it in your inbox. - **Rescue from Junk:** with Learn from Junk (on by default), AutoSPAM reads your Junk or Spam folder daily, moves mail from senders you know back to your inbox and learns the remaining senders as spam. - **Known senders stay safe:** AutoSPAM reads your Sent folder and adds the people you write to to the allowed list, so they are never blocked. - **Unknown senders are checked:** new senders are analysed by content and behaviour. Uncertain ones can wait in _AutoSPAM/REFUSED instead of your inbox (optional). - **The folder is the teacher:** drop an email into _AutoSPAM/SPAM to block the sender's domain, into SPAM_ADDRESS to block one address, into ALLOW to always let the sender through, or into VIP to star the sender's emails in your inbox. One move is remembered. - **Not spam, just unwanted:** on higher plans, _AutoSPAM/UNWANTED learns a type of email, such as a shop's newsletters, without blocking the sender, so the same shop's invoices still reach you. - **Housekeeping:** duplicates go to _AutoSPAM/DUPLICATES and read receipts and delivery notices to _AutoSPAM/SYSTEM. Dangerous attachment types such as executables, macros, disk images and scripts can each be blocked with their own switch. - **Every decision explained:** the Logs tab and the _AutoSPAM/LOGS folder in your mailbox say why each email was moved, and a mistake is undone by moving the email back or with one button. - **One rule set for all mailboxes:** your lists are stored at BOTS4.me, not in a mail app, so they apply to every connected mailbox, across Gmail, Microsoft 365 and IMAP, and survive a change of device or provider. AutoSPAM is also the front door for BOTS4.me's ERP bots. With pre-processing switched on (Team plan), new mail first lands in _AutoSPAM/QUEUED, and Mail2ERP, Supplier2ERP and Pay2ERP read their emails from there, so only mail that still needs a person reaches your inbox. ## 📊 Side by Side | Criterion | Gmail / Google Workspace | Outlook / Microsoft 365 | AutoSPAM | | --- | --- | --- | --- | | Where it works | Google's servers, before delivery | Microsoft's servers, before and after delivery | Inside your mailbox, after the provider's filter | | Main decision | Inbox or Spam (or admin quarantine) | Inbox, Junk Email or quarantine | Inbox, or one of the _AutoSPAM folders: SPAM, REFUSED, SUPPLIER, UNWANTED, SYSTEM, DUPLICATES, your own lists | | How users teach it | Report spam / Not spam, contacts, filters, block | Safe Senders, Blocked Senders, Report | Drop an email into a folder or click a button in the LOGS folder | | Admin allow-lists | Approved senders lists, internal bypass | Admin-managed lists and policies | Shared lists across all connected mailboxes; monthly list export to share | | Mail in Junk or Spam | User checks the Spam folder | User checks Junk; admins release from quarantine | Read daily; mail from known senders moved back to the inbox | | Mixed providers | Google mailboxes | Microsoft mailboxes | Gmail, Microsoft 365 and IMAP mailboxes with one rule set | | Included in | Your Google account or Workspace subscription | Your Microsoft 365 subscription | A separate app with a free plan; first month free | ## ✅ When the Built-in Filter Is Enough Many companies need nothing more than what Google or Microsoft already provide. That is likely true for you when: - Little spam gets through, and real mail rarely lands in Spam or Junk. - Someone checks the Spam or Junk folder and the quarantine regularly, and knows how to release a message. - An admin keeps approved senders, Safe Senders and blocked senders in order for everyone. - All your mailboxes are on one provider. - Newsletters, notifications and unknown senders in the inbox do not bother you, or your users handle them with their own rules. In that situation, tune the built-in tools first: mark false positives as not spam, add important customers and suppliers to your contacts or Safe Senders, and ask senders whose mail keeps landing in spam to set up email authentication for their domain. ## 🔧 When AutoSPAM Is Worth Adding - **Orders or supplier replies have been found in Junk** more than once, and checking Junk by hand is easy to forget. - **The inbox is spam-free but still crowded,** and you want newsletters, notices and strangers out of the way without blocking anyone important. - **You run several mailboxes,** perhaps on different providers, and want to teach them once. - **You want to see why** each email was moved, and undo it with one move. - **You use or plan Mail2ERP, Supplier2ERP or Pay2ERP,** and want only sorted mail to reach them. ### 🧪 Try it without risk New AutoSPAM accounts start in Demo Mode: AutoSPAM judges every new email exactly as it would live, but moves, deletes and flags nothing.

No. The provider's filter keeps running first and blocks or files a large share of spam and malicious mail before AutoSPAM sees it. AutoSPAM works inside your mailbox on top of that: it sorts what arrives, reads the Junk or Spam folder and moves mail from senders you know back to your inbox. ### Why do important emails end up in the Outlook Junk folder or Gmail Spam? Built-in filters judge every message automatically, and no filter is perfect, so a legitimate order or reply is sometimes classified as spam. In Microsoft 365 the anti-spam policy decides whether such mail goes to the Junk Email folder or to quarantine; in Gmail it goes to Spam. Marking it as not spam, adding the sender to your contacts or Safe Senders, or an admin allow-list helps for that sender. ### How does AutoSPAM rescue mail from Junk? Learn from Junk is on by default. AutoSPAM reads your Junk or Spam folder every day: mail from senders you know, such as people you have written to, is moved back to your inbox, and the remaining senders are learned as spam and their mail moves to _AutoSPAM/SPAM. ### Does AutoSPAM work with both Gmail and Microsoft 365? Yes. Gmail and Google Workspace, and Outlook and Microsoft 365, connect with Secure Quick Connect; Yahoo and other providers connect over IMAP with an app password. Several mailboxes on different providers can share one set of lists. ### Will AutoSPAM delete my emails? Not by default. AutoSPAM moves mail into _AutoSPAM folders where you can see it. Automatic Clean-up, which removes emails older than 30 days from AutoSPAM's SPAM, DUPLICATES and SYSTEM folders and from the native Junk and Trash, is available from the Business plan and is off until you switch it on. ### Does AutoSPAM send my email to an AI provider? Only if you want it to. With AI Mode set to Off, AutoSPAM keeps filtering with content scoring, sender reputation, your lists and a statistical filter trained on your own mailbox, and no message is sent to an AI provider. ### When is the built-in filter enough on its own? When little spam gets through, when real mail rarely lands in Spam or Junk, when one person or an admin keeps the allow and block lists in order, and when you only need spam versus not spam rather than sorting newsletters, notifications and unknown senders. ### What happens after the free Discovery month? AutoSPAM continues on the free plan by itself with a small monthly allowance and no time limit: manual controls plus blocking of executables, disk images and scripts. AI sorting and the other automatic features need a plan. ## 📚 Related Reading - **Product and guides:** [AutoSPAM product page](https://bots4.me/product/autospam/), [AutoSPAM Guide](https://bots4.me/autospam-guide/) and [AutoSPAM Quick Reference](https://bots4.me/autospam-quick-reference/). - **Step by step:** [How to Stop Spam Permanently for Your Whole Company](https://bots4.me/stop-spam-permanently/). - **The bigger picture:** [Email Automation for Small Business: Spam, Backup and Orders Handled](https://bots4.me/email-automation-for-business/). - **Keep a copy of everything:** [How to Back Up Office 365 or Gmail Email to Your Own Cloud](https://bots4.me/backup-email-to-your-own-cloud/). - **What comes after a clean inbox:** [Parseur, Docparser or Nanonets vs Mail2ERP for ERP Order Entry](https://bots4.me/email-order-parsers-vs-erp-automation/). - **Reading the logs:** [The LOGS folder in your mailbox](https://bots4.me/guide-logs/). ## 🔗 Sources Facts about Gmail and Microsoft 365 are taken from Google's and Microsoft's documentation as it read on 29 October 2026.
