What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 27 of the 57 other email marketing and newsletter tools we grade
MailBluster is an email marketing platform that does not charge by list size. You can connect your own SMTP provider such as Amazon SES, Postmark, Mailgun or SMTP2GO and pay MailBluster a small subscription plus a per-email fee, or have MailBluster send for you on a Managed plan priced by monthly email volume.
To get you started, here are 9 things to know about MailBluster, taken from its own pages and our grades.
A web app where you connect your own SMTP provider on the cheaper plans, which is setup work.

The report card
Best for senders who bring their own SMTP and want low fees
MailBluster charges a small monthly fee plus $0.60 per 1,000 emails, and you bring your own SMTP provider such as Amazon SES. That keeps the price low but adds a second bill. The free Starter plan caps at 3,000 emails in total, not per month, and keeps MailBluster branding.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | $5 a month plus $0.60 per 1,000 emails on yearly billing is inside the cheapest quarter, before your SMTP provider's fees. A managed plan with sending included is $15.30 for 10,000 emails. |
| Free plan and trial | C | Starter is free with your own SMTP, but it allows 3,000 emails in total and keeps MailBluster branding. There is also a 14-day trial of Managed plans with no card. |
| Features | C | Unlimited leads, automation, A/B testing, custom fields, a WordPress plugin and API access. The listing shows no forms or landing pages. |
| Ease of use | C | A web app where you connect your own SMTP provider on the cheaper plans, which is setup work. No rating on record. |
| Platforms and integrations | B | Web only, with WordPress, WooCommerce, Salesforce, Zoho, Zapier, Make, Pabbly Connect and Amazon SES. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who MailBluster is for
- Fits if you already have an Amazon SES account and want to avoid list-size pricing
- Works for ecommerce senders on WordPress or WooCommerce
Who it is not for
- Tight if you stay free: 3,000 emails in total, not a month
- Watch out: your SMTP provider bills you separately, and Amazon SES adds a small SNS charge past 100,000 requests
- Watch out: Pro and Executive are shown only as billed yearly, with no monthly price
- Skip it if you want one bill, as the managed plans cost more and stop at 250,000 emails a month on the page
- Not for you if you want a mobile or desktop app, as it is web only
Good to know
Good for
- Senders with large lists who want to avoid per-contact pricing
- Technical users comfortable setting up Amazon SES or another SMTP provider
- Teams that want sending handled for them on a Managed plan
Worth knowing
- With your own SMTP, provider fees are extra; Amazon SES also adds a small Amazon SNS charge past 100,000 requests a month.
- The Starter plan allows 3,000 emails in total, not per month, and keeps MailBluster branding.
- Managed plans cover up to 250,000 emails a month on the page; above that it is sold through sales.
- Pro and Executive are shown as billed yearly, and the page does not show a monthly price for them.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace MailBluster you would be making newsletters sent to thousands of people that still reach the inbox. That is not a weekend's work, with an AI app builder or without one.
It costs $60 a year.
What you could not
- Newsletters sent to thousands of people that still reach the inbox.
- Email sent in volume that still reaches the inbox.
- Mail servers with a good name among inbox providers.
- Splitting visitors between versions and telling you which won.
- It plugs into other products, WordPress, WooCommerce and Salesforce among them, and has an API.
