see like this, what would you do if gym shark sent you an email or any other good brand on IG. Credibility is built through hard work. High-level content, good products or service, professionalism, social proof.
High quality stuff, high results.
Scammy low level stuff, low results.
People have the idea that because you are sending bulk emails, you are "spaming" therefore they see it as a pump and dump (rug biz) making low-quality funnels and overall presence.
By definition, it's "spamming". But that doesn't mean you can't send good emails, where the outcome is positive, profitable and is a win win for everyone. Why would i send a email 1 at the time, if i can find ways to send more? it's just speeding up the process.
So yeah if you have long-term vision and believe in what you are selling you shouldn't have a problem in converting
