What to do to send a large bulk of emails?

The best recommendation would be to connect aNinja with a Transactional Email service provider (such as Sendgrid). You’ll then be able to send 10K to 1M+ eventually emails without affecting your email provider.

Moreover, Sendgrid adds Unsubscribe links with the emails you send through it. It also tracks spam score and notifies you.

SendGrid is usually used to send out bulk email sequences and it works well with aNinja.
