Hello and thank you for contacting us. This is Dwayne B. and I’m an expert here and looking forward to assisting you today.

Also, I can only answer the questions you specifically ask and based on the facts that you give so please be sure that you ask the questions you want to ask and provide all necessary facts.
You aren't supposed to have direct contact with the attorney for the estate if you have an attorney. If you do, then that can cause issues later if the estate attorney contacts you when they are not supposed to.
In addition, it is always a good idea to follow your attorney's advice regarding matters like this since they know what the ultimate case strategy is. While I don't see this specific issue here, sometimes by sending materials to the other side you can waive privileges, open the door to the admissibility of some evidence that wouldn't otherwise be admissible, etc.
It is also unlikely that the attorney for the estate will look at the items you send for more than a moment or two and so won't likely give them much consideration. Most lawyers would then seal them in an envelope with the date they were delivered and they may even file a motion with the court asking the court to order you to contact the only through your attorney and the court would/could then order you to pay the attorney's fees involved in filing the motion and having the hearing.
Thus, essentially what you would end up doing is potentially causing bad results with little to no reasonable expectation of good results.
