Question
I am the Co-founder of Grizly.com. We are beginning to scale up our email marketing strategy and are getting ~1,000 emails/day. I think it will be closer to 10K leads/day at scale. We send each lead an autoresponder of ~20 emails/month. So we'll likely be sending millions of emails a month by Q2. What is the best and safest software to manage our email campaigns? Mailchimp and SendGrid both seem too expensive.
Answer
I will recommend you to use EasySendy, Vero or AutoPilot. You should know anyway than sending emails is expensive and that should be considerate in your costs.
