Thanks for checking in! Honestly, every agent has a different response time, and those times vary depending on what's going on. For example, if we've been away to a conference, not only is that time for queries to pile up, but once we return, we often have a slew of more queries to contend with. Plus there are times when we are exceptionally busy with existing clients.
One month isn't much time when it comes to waiting for a query response. I'd give it a few months before checking in with her to follow up.
