Pick MailBluster if
- Fits if you already have an Amazon SES account and want to avoid list-size pricing
- Works for ecommerce senders on WordPress or WooCommerce
Look elsewhere if
- 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

- Works for agencies that run a PHP host and want to give each client a branded account with its own limits
Look elsewhere if
- Skip it if the words PHP, MySQL and Amazon SES make you nervous, as you set them up
- Not for you if you want to try it first, as there's no trial, only a refund
- Tight if you run several sites, since each license covers one domain
- Watch out: major version upgrades aren't included, and the AI add-on is $39 and installation $79
- Too light for anyone wanting a phone app or a hosted service, as it runs only on your own server
How we grade them
| 2.4GPAMailBlusterFair | 2.0GPASendyFair | |
|---|---|---|
| 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. | A$69 once for one domain, less than half a year of this category's middle subscription. Sending is Amazon's $1.6 per 10,000 emails, paid to Amazon. Add your own server, $79 if you want Sendy to install it, and $39 for the AI add-on. |
| Free plan and trial | CStarter 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. | FNothing is free and there's no trial. Sendy promises a refund if it doesn't work out, but a money-back promise isn't a trial. |
| Features | CUnlimited leads, automation, A/B testing, custom fields, a WordPress plugin and API access. The listing shows no forms or landing pages. | CThree editors, autoresponders on intervals or dates, rules and webhooks, segments, custom fields, live reports, automatic list cleaning and white-labeled client brands. It does newsletters fully, but it's a smaller job, and it can't send without your own Amazon SES or SMTP account. |
| Ease of use | CA web app where you connect your own SMTP provider on the cheaper plans, which is setup work. No rating on record. | DNo App Store rating on record, and you install it yourself on a PHP and MySQL server and set up your own Amazon SES account. That's self-hosting, which puts it at a D. Sendy will install it for $79. |
| Platforms and integrations | BWeb only, with WordPress, WooCommerce, Salesforce, Zoho, Zapier, Make, Pabbly Connect and Amazon SES. | BIt runs in a browser on your own server, with Amazon SES, SendGrid, Mailjet, Elastic Email, Zapier, WordPress, Magento and Joomla, plus an API. No desktop or phone app, so a B. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
