Someone may find it difficult to find the email address of their Reddit account because Reddit was designed with anonymity in mind. Email addresses are not publicly shown in connection with accounts on Reddit as on other platforms. This is not a coincidence in design; users are free to interact without providing personal information. The first thing to know is this before attempting to contact another person using the internet in the context of their privacy and boundaries being respected.
Reddit has a private message or chat feature that is one of the effective means to contact a Reddit user. Go on their profile and search the "Chat" or the Message option, and then send them a polite message. Explain the purpose of your contact with them and (thoughtfully) request them to provide their email address. By providing them with the option, you remain respectful to their privacy and be professional.
When the messaging is disabled, it is possible to visit their profile on Reddit to get a clue. Certain users post their contact details in the bio, or post history, or comments in subreddits. Find words such as, contact me, reach me, or links to social media. This must be done ethically and very carefully not to infringe the community rules of reddit or interfere with the privacy of the user in any manner.
It can also be useful to interact with the person publicly with comments. Thoughtful commenting on their posts develops trust in the long run. Having gotten a good interaction they may voluntarily give you their email. This is a less intrusive method, and allows a more natural discussion that can result in the discovery of ways to communicate with people beyond Reddit without violating personal space.
Lastly, in case you want to be professional, you can make a post publicly in a subreddit. Explain what you want, give your personal contacts and ask the individual to communicate to you. It is an open and transparent method and complies with the rules of Reddit and provides the user with complete freedom on whether to connect with you or not.
Conclusion
Locating an email address of a person using Reddit can be done with respect, patience, and ethical standards. The access is not direct so the best bet is to use private messages, see the public profiles or get involved publicly. Always remain open about what you intend and don’t use pushy strategies. To preserve anonymity of the user, communication is consensual and professional as well as within the community rules of Reddit, ensuring that to protect both sides of the interaction.
