View attachments and open external email links
Preview supported files and inspect URLs before opening them.
View or download a file
Open a message and use its attachment actions. Images, PDFs, and supported text files can be previewed. Other file types show a download option so you can use an appropriate installed application. If a file is not cached locally, refresh the account and try again.

Open a link safely
- Click a link, button, or URL-backed attachment in the message.
- Read the External URL confirmation. Long addresses are visually shortened; use Copy to inspect the complete address.
- Choose Open now to open it in an external browser, or Cancel.
The operating system's configured browser determines which external browser opens. AeroMailer does not guarantee using an arbitrary already-open Chrome, Edge, or Opera window.
Remote images and untrusted files
Remote pictures require network access and an available image host. Loading a remote image can contact its host. Do not open unexpected files or enter credentials on a linked page merely because the message looks legitimate.
Open, print, or save message files
Use the message menu to print, download an .eml copy, or see the raw message in Show original. Open supported .eml and .emlx files with AeroMailer; use Reply or Forward with a valid SMTP account. Choose AeroMailer as the default mail app for supported files and mailto: links where offered; the operating system may require confirmation.
