So, I've got this long list of potential sponsors for an online campaign. Of course I'd e-mail them. Let's say it's around 100 e-mails that should be sent in a matter of weeks. I'd prefer them sent from my Gmail account, since I'd like the companies to reply there... It would be an offer that's pretty much the same for everyone, I wouldn't have time to personalize it. So yeah, it's not much (the number) but I'm afraid Gmail wouldn't like it. I don't want the messages to end up in spam. What should I use? Free, if possible. And no proxies etc, pretty please, never got into that nor I think I'm able. Thanks in advance! I did search on BHW, found this thread, currently downloading SendBlaster 2 but I'd like to hear some advice from you guys & say something about my situation. I'm also checking out SendGrid, they have a free plan.
