Mailgun vs SendGrid – Best Transactional Email Services

Mailgun vs SendGrid

Most successful marketers know that email marketing is still one of today’s best and most effective marketing methods. So yes, even with social media marketing on the rise, email marketing is still pretty much king.

Most businesses still use email marketing as one of the pieces of their overall online business strategy.

Of course, you are not going to send emails manually. That would be a colossal waste of time. Imagine it; you write emails and send them to customers and potential customers one by one. Just thinking about it hurts. It does.

Thankfully, we have STMP providers that can do the job for us or make it way more accessible than it used to be.
