What SendLater is
SendLater is a Windows add-in for Microsoft Outlook that schedules email messages for a chosen time. Its free edition schedules each message once, with resend delays limited to four hours. Pro adds recurring schedules—daily, weekly, monthly, yearly, or custom—and can send follow-ups at intervals until a reply arrives. With an Exchange or SMTP account configured, scheduled messages can be sent while Outlook is closed. Pro also offers DocTrack for sending linked documents when they change, and can provide the latest version of a linked file or folder on schedule. For group email, it can send one message to all recipients or separate copies that hide the other recipients; it can also load recipients from a CSV file. The free plan costs nothing. Pro full license is $39.95, paid once and includes one year of updates and support. Listed requirements include Windows XP SP2 through Windows 10 and Outlook 2003 through Outlook 2019 32-bit, plus Microsoft 365; Outlook for Mac is not supported.
