Hello Sunit,
my best advice is to have a standing order 125 TCredit.
This puts you in a position to obtain 1,500 Vp and become automatically EA. Investing in 15/25 PSA month with the purchase of PSA.
Become BTL and get a share of 45/50 CSA.
Keep fearless this design and will soon be possible to achieve success.
This I believe is the most economical method to avoid the hard work to send e-mails. For me it worked and I hope so for you.
Best wishes.
