Most G2 reviewers work at companies with 50 or fewer employees, and 129 of the 231 reviews we pulled are marked as incentivized. Reviewers praise how fast SaneBox learns from drag-and-drop training, the SaneLater and SaneBlackHole folders, and a setup that takes minutes. Complaints are rare and mild: the filter needs some early training, and a few people still check their folders for misfiled mail. Reviews cluster in 2021 and mid-2026, when invitation campaigns ran.

Email Under Control: Digest Scheduling and SaneBlackHole Are Game-Changers

Inbox clarity and empowerment What they like: SaneBox has allowed me to truly put a "container" around my email. Instead of being constantly interrupted, I have it set up to open my digest at 2:00 PM each day. By the time I open it, I feel completely empowered and in the right headspace to review what’s accumulated in my SaneLater and SaneNews folders. I also absolutely love the SaneBlackHole feature. It is incredibly satisfying to drop random, unwanted emails in there and know I’ll never have to deal with them again. Highly recommend! What they dislike: Honestly, there isn't much to complain about. It takes a few days of training to get the filters exactly where you want them, but the AI learns incredibly fast. It's well worth the tiny initial effort.

SaneBox: Effortless Email Management

SaneBox filters out unimportant emails, saving me at least 5 hours each week and lets me focus on more valuable tasks. What they like: I love how SaneBox manages all the clutter in my e-mail inboxes by catching unimportant mail and filtering it into other folders, and it also flags important e-mails for my quick response. Since using it, I've saved at least 5 hours each week because I don't have to manually manage my inbox. The extra time I save allows me to spend more time on other activities. The initial setup was very easy, just by pointing it at my e-mail inboxes, and it created an API token to start sorting e-mail immediately. I find the web app very easy to follow, and it's great that I can use SaneBox with both Outlook and Gmail. What they dislike: The mobile app could use some better organization in the UI.

Its simple features like SaneLater and SaneNews help limit distractions and keep my inbox organized. What they like: I really appreciate how SaneBox helps me manage my emails by separating what's important from what can wait, which reduces distractions in the morning. I value the organization it brings, especially with the Sane Later and Sane News features. They're simple and limit distractions effectively. Even with the simplest usage, it's terrific. The initial setup was very easy, even for someone like me who isn't into complicated systems. SaneBox is so helpful it feels like having an assistant, and I'd rate it a 10 for recommendation. What they dislike: nothing to dislike

Sanebox .... it made me sane again

Sanebox helps my business sift through spam emails that could otherwise impact the business in a negative way. When you consider that an employee can spend 10–15 minutes per day moving and deleting spam emails, that’s a huge amount of time saved. What they like: It’s so easy to set up and use on a daily basis. It has already saved me a lot of time, and I feel my company is a bit more secure now because the bad emails are being filtered out before they reach my inbox. What they dislike: I can’t really say anything bad about it. Everything works perfectly.

Inbox Zero Made Effortless with Sanebox

Sanebox solves the clutter that used to live in my Inbox. Now, each message is quickly organized in easy to locate folders with actions to handle those messages much quicker. SaneLater and SaneNews help to move messages where they belong and allow me to read through them when I have the time throughout the day. And SaneBlackHole is a great option for discarding stuff you may want occasionally but for the pesky senders that like to email every hour. What they like: Sanebox is essential to maintain an Inbox Zero setup. I have been using Fastmail for years, and recently tried Sanebox. Now I can't live without it. My email is easily managed and every message is actionable without much hassle. Fastmail + Sanebox is a great combination. What they dislike: Nothing. Everything about Sanebox has been great. I paid for my subscription before my trial ended because I felt so confident in how it was improving the way I use email.

Effortless Inbox Management with SaneBox

SaneBox keeps my inbox clean, sorting unwanted emails into a black hole and questionable ones into a review folder. It learns over time, helping me prioritize effectively, so my inbox stays manageable and nothing important gets overlooked. What they like: SaneBox has really been a lifesaver for managing my inbox. I appreciate that it can automatically sort emails into categories, putting the unnecessary ones into a folder that gets deleted over time, and others into a "sane later" folder for me to review daily. It's pretty amazing how it's able to learn what's a priority and what's not. Thanks to this, my inbox is always clean, and I reach inbox zero each week without missing anything important. I like that I didn’t have to change my primary email address, which would have been disruptive, because my inbox remains organized. The AI seems well-tuned in deciding what's important for me and what’s not, making sure I can review anything questionable. I also appreciated how easy it was to get SaneBox up and running—it sorted emails instantly and was helpful from the get-go. I use it with Outlook and appreciate its ability to learn from how I sort emails, which helps keep my inbox clutter-free. What they dislike: No issues with SaneBox.

Transforms Inbox Management with Ease

SaneBox organizes my inbox, keeping important emails visible and categorizing others into subfolders. It frees up my time to focus on crucial tasks by learning my reading habits and helps me efficiently read and address emails. What they like: I use SaneBox to organize my inbox, and it effectively leaves important emails in my inbox while moving other emails into different subfolders, like news-related emails into a news subfolder. This helps me utilize my time reading and addressing emails efficiently. SaneBox has freed up a lot of my time as I can focus on what is important. The initial setup was very easy, and I was up and going in less than an hour. It does a great job, and I highly recommend it. What they dislike: I cannot think of anything

Effortless Inbox Management, Worth Every Penny

SaneBox organizes my work and personal inboxes, reducing overwhelm and anxiety. It prioritizes important emails and sorts newsletters and spam, enhancing my email management. What they like: I like how easy SaneBox is to implement, and I appreciate the speed of its use. The setup took less than a half hour and was very quick and easy. I love that it constantly learns how to sort emails according to my preferences, which saves me from needing to hire an assistant. SaneBox eliminates the anxiety and overwhelm of managing my email inbox by sorting newsletters, receipts, and spam to ensure I only see what's important. What they dislike: I do wish that there was a way to tell it that not everything from the same domain goes to the same place. Prioritizing things by sender would be great.

SaneBox helps me focus on high-priority emails and organizes my emails by category. It addresses my overwhelming inbox, allowing me to find important emails easily. The setup was incredibly easy and intuitive, making it simple to use. What they like: I use SaneBox for organizing my emails by category, allowing me to focus on high-priority emails without getting distracted. I like how easy and intuitive it was to set up and use, and it was up and running within thirty minutes. The SaneBox black hole feature that automatically unsubscribes me from unwanted emails is awesome. The team's responsiveness in making adjustments and helping me learn about the features is something I appreciate. I didn't find SaneBox earlier, but now it's my go-to email management system, and I’m happy to recommend it to everyone. What they dislike: There isn't anything that I don't like about it.

Effortlessly Focus on Important Emails

SaneBox helps me focus on important emails, reducing distractions from unimportant ones. It allows me to manage emails at my preferred frequency and keeps my inbox organized so I don't feel overwhelmed. What they like: I like that SaneBox can help me get my inbox to zero if I wanted to, which is great because I get anxious when I have pending emails. It helps me organize without being overwhelmed, focusing on important emails and allowing me to check them with the frequency I want. The initial setup was simple. What they dislike: I find the beginning a bit challenging because I need to train the AI on what is important and what isn't. Sometimes important emails get relegated to the Sane Later folder, so I have to be on top of that.

Keeps My Inbox Organized and My Workflow Stress-Free

SaneBox literally keeps my mailbox sane. It automatically sorts email into categories once you’ve trained it, and the Blackhole for spam means I never have to see those messages again. There’s also a CC folder, so anything I’m CC’d on goes straight into that mailbox, etc. Overall, it makes the daily flow of incoming email much more efficient, so I’m not wading through spam just to get to the actual work emails. What they like: It keeps my workflow clean and tidy. The filters I’ve set up for sorting my emails make my day feel much less chaotic. What they dislike: I dont have any particular dislikes, I thinks its a good tool.

Effortless Email Management with SaneBox

I find SaneBox simplifies my email management by sorting my emails into compartments like Inbox, SaneLater, and SaneNews. It helps in identifying important emails easily and is simple to set up. What they like: I love how simple SaneBox is to set up. It just connects and links with my Fastmail account and works out of the box, creating three compartments: important emails in Inbox, less important ones to SaneLater, and those not important at all to SaneNews. I find this organization incredibly helpful. The AI used in SaneNews and SaneLater to sort all the emails is fantastic, and the value for the price is great. What they dislike: There's a problem with SaneBox when it comes to handling notifications for important emails. I use Fastmail, and it's tricky because I can only choose between getting notifications for all emails or just selected VIP ones. I can't get notifications specifically for those that end up only in the inbox, which is something SaneBox based on IMAP doesn't currently support.
