The sentence is incorrect, and it's either a grammatical mistake that "to" is not supposed to be there or a typo for "not." Unfortunately, these are opposite conclusions, and a bit of context would be helpful.
I would strongly guess it's the former, because putting "to" before the verb is the infinitive form and while "to" doesn't go before the gerund, that's an easily understandable mistake, especially if English is not the recruiter's native language. If other parts of the message contain information about how to apply, that is further evidence supporting this interpretation.
You could reply with something like "Great! I will get my application in soon" to communicate what your understanding was (assuming you do intend to apply soon) and if "not" was intended the recruiter should correct you.
