It would be Anne that likes/loves the text in quotation marks.

Under the covers the Spanish phrase means "someone loves something" (here, 'love' means 'taking delight in something' - do not confuse this with affection). The "someone" isn't provided (there is no person mentioned). The "something" is your message.
Here is the Spanish phrase model (the model is not conjugated, and must be in order to convey meaning): encantarle algo a alguien

No one would compose the SMS text you received. That's why I believe it was computer-generated. It isn't the way a native speaker would write.

The conjugated phrase that you received (which doesn't contain all of the components of the model):
le = (to) someone (the word 'le' stands in for, or represents, the person indirectly liking the "something" - 'le' was tacked onto the end of 'encantar' in the model, but when the phrase is conjugated, it is moved prior to the verb)
encanta = loves (likes a great deal - delights in)
algo = something (that something is provided in your text (enclosed in quotation marks))

Missing from your text:
a alguien = (to) someone (this is where "a Anne", or "a ella" could have appeared) (This missing part could have preceded 'le' or followed the verb, prior to or following the 'algo' part of the message. It's not a requirement to have this missing piece, especially when both involved in the conversation know who is indirectly affected by the "something".) (It's also not a requirement to specify the "something" part. In English we have to say "it". That little word isn't used in Spanish (not in this case, at least). So, 'le encanta', all by itself, is translated into English as 'Someone loves it'.)

I hope this information helps.
