The English phrasal verb 'send out' covers several related meanings: dispatching something physically, emitting signals or light, issuing invitations or announcements, and radiating a feeling or impression. Japanese uses different verbs depending on what is being sent and how.
To send something (a letter, package, goods) to a destination, often via postal service or courier.
General verb for sending something. Works for letters, packages, emails, etc.

In many cases, the most natural Japanese expression does not use a direct translation of 'send out'. For example, 'send out a search party' is 捜索隊を出す (そうさくたいをだす) or 派遣する (はけんする), not 送り出す. Consider the object and context.
出す (だす) means 'to put out' and is used for emitting or issuing things from a source. 送る (おくる) means 'to send' and implies transmission to a destination. Use 出す for light, sound, signals, and issuing notices; use 送る for mailing, shipping, or transmitting to a recipient.
太陽は熱と光を発する。
The sun sends out heat and light.
花が強い香りを放っている。
The flowers are sending out a strong fragrance.
