What the experts say6Expert opinions
Expert from Email Geeks shares that Microsoft doesn't react as nimbly as Gmail does, and reputation is a measure of past performance. It takes as long to fix a reputation as it did to create it. There's no shortcut. You may be able to open a ticket through their support page and ask for mitigation, but if you've not fixed the underlying causes, you'll end up back in the same place.
Expert from Email Geeks advises against using tools like Inboxally and Warmbox to repair reputation. Microsoft has sued people for creating lots of accounts to move mail from spam to the inbox and create a fake reputation. Google has cut off API access for companies that do this, and Yahoo said in a different thread on the topic it was against their AUP because they are companies built on abusing the system.
Expert from Word to the Wise shares that Microsoft has unique filtering practices. They recommend focusing on list management, opt-in processes, and providing value to recipients, as Microsoft prioritizes user engagement. They also recommend monitoring the volume and frequency of your sends.
Expert from Spam Resource explains that using Microsoft's SNDS (Smart Network Data Services) and JMRP (Junk Mail Reporting Program) are important for monitoring your IP reputation and understanding how Microsoft views your email traffic. Regularly checking these tools can help identify and address issues affecting inbox placement.
Expert from Spam Resource explains that Microsoft's filtering is heavily reputation-based and can be challenging. Focus on consistent volume, low complaint rates, and authentication to build a good sender reputation. Also, Microsoft weighs content and engagement very heavily.
Expert from Email Geeks explains that Microsoft has different standards for senders and are much more sensitive to their user's reactions to mail. The underlying issue is sending less mail that recipients are interacting with negatively, which impacts the reputation at Microsoft. This may mean setting up a different flow and sending less mail to Microsoft users. Gmail will allow you to annoy recipients into purchasing, Microsoft may not.
