Email Marketing Pricing Models Explained

Understanding pricing models is critical the wrong choice can cost you 5-10x more than necessary.

Pay Per Subscriber

You pay based on how many contacts you have, regardless of how many emails you send. Price increases as your list grows.

Used by: GetResponse, Constant Contact, MailerLite

Best when: Small list, frequent sends (daily/weekly newsletters)

Pay Per Email

You pay based on how many emails you send, with unlimited contacts. Price increases with send volume.

Used by: Brevo

Best when: Large list (10K+), moderate sends (1-4x per month)

Example: 50,000 contacts, 2 newsletters/month. GetResponse: ~$299/mo. Brevo: $25/mo (20K emails). That is a 12x price difference for the same result. Always calculate based on your actual sending pattern.

Frequently Asked Questions

What is the average ROI of email marketing?
According to Statista and Litmus, email marketing returns an average of $36 for every $1 spent a 3,600% ROI. Some industries see even higher returns: retail and e-commerce average $45 per $1 spent. This makes email marketing the highest-ROI digital marketing channel.
Which platform has the best free plan?
It depends on your needs. Brevo offers unlimited contacts (300 emails/day) best for large lists. MailerLite offers 1,000 subscribers with 12,000 emails/month best for small creators. GetResponse offers 500 contacts with unlimited emails best for testing automation features.
How important is deliverability?
Critical. A 5% difference in deliverability means 5% of your emails go to spam instead of inbox. On a 10,000-person list, that is 500 people who never see your message. In our testing, MailerLite (95%) and GetResponse (95.7%) led on deliverability.
Do I need automation?
If you have more than 500 subscribers, yes. Automated welcome sequences, abandoned cart emails, and re-engagement campaigns run 24/7 without your involvement. Automated emails generate 320% more revenue than manual sends (OptinMonster). All 4 platforms we tested include automation.
Can I switch platforms later?
Yes, but it is not easy. You can export contacts via CSV, but email templates, automation workflows, and subscriber engagement history cannot be transferred. Choose carefully upfront migration takes time and you may lose some data.
Is Mailchimp better than these options?
Mailchimp is the most well-known but not the best value. It charges per subscriber (like GetResponse) but with fewer features and higher prices at scale. GetResponse and Brevo both offer more features per dollar. We chose not to review Mailchimp because these 4 platforms consistently outperform it on value.
