Question before I buy Email Spider

Hi @Sven

Have some questions before I buy this soft.

I need to send around 5000-10000 emails per day, Customer will not send a reply to, or a feedback, to the @from email address, they will just click a link to a webpage, in the message. I know that it wasn't build to send things like that, and I'm not interested to use this program for Spam, but I'm interested to reduce the costs with sendgrid, and use fake email addresses as sender, because my email provider doesn't let me to send more than 500 emails per day. The question is if that's possible?

I mean if i set %random%@{live.com|gmail.com|otlook.com|random-domain.com} as sender, will the software work, and send the newsletters? Do I need to add other settings? Sorry if this question sounds stupid but I'm noob in using the email spider software.

What is the best way to set Email Spider to send 10k emails per day, without using sendgrid, considering that I also can't use my email provider because he limits me to 500 emails per day per domain?

My second question. I also own GSA SER, and Indexer. Is it possible to give me a discount?

Thanks
