How to Set Up, Configure, and Send Emails using AOL SMTP Server

AOL SMTP enables users to send email from an AOL Mail address through compatible clients and applications using smtp.aol.com with SSL on port 465 or TLS on port 587, a full AOL email address, and an AOL-generated app password. Configuration requires enabling two-step verification and creating an app password, which can then be used with services such as Gmail, Thunderbird, and Outlook; incoming mail can be retrieved through POP3 at pop.aol.com on port 995 for local downloads or IMAP at imap.aol.com on port 993 for server-synchronized access. Common setup problems include incorrect credentials, failure to use an app password, mismatched ports or encryption settings, blocked connections, and AOL-side timeouts. Although AOL SMTP is free, widely compatible, and relatively easy to configure, it limits users to 100 messages per day, 500 daily recipients, 100 recipients per message, and 25 MB messages, making it less suitable for bulk or business email campaigns; the text presents Mailtrap as a scalable alternative with higher throughput, bulk sending capabilities, analytics, and integration tools.
