To run the script, you need to install the required Python packages. You can install these packages using pip:

pip3 install -r requirements.txt

To warmup an account by sending 5 emails to a single target, use the following command format:

python3 Warmer.py -u <Email ID to Warmup> -p <Password> -T <[email protected]> -m 3 -x 5

To warmup an account against a list of targets from a file, use the following command format:

python3 Warmer.py -u <Email ID to Warmup> -p <Password> -t <send_to_list.txt> -m 1
