grammar - Which one is more appropriate: To learn more about or For more information

When sending a formal email, which of the following sentences is more appropriate to use:

1. To learn more information, please visit helloworld.com.




2. For more information, please visit helloworld.com

Also, using To learn more information... has any grammatical issue? Is there any reason why you should not start a sentence with an Infinitive Verb?

Answer

To my ears "for more information..." sounds more natural. An Ngram with both phrases shows that "for more information" is far more common. I would probably use "for more information," even though neither are wrong per se.

To answer the other question, there is nothing ungrammatical about starting a sentence with an infinitive, as discussed in this post: Can I start a sentence with To + verb?.
