What Is MailBluster?

MailBluster is an email marketing platform that helps businesses send bulk campaigns and newsletters to subscribers. Users can create responsive emails with a drag-and-drop composer and group the leads based on their email engagement or the products they have purchased. The platform also lets users send two versions of a campaign to compare which one generates more conversions. It connects with multiple SMTP providers for email delivery.

What Is MailBluster Best For?

MailBluster excels at email segmentation that enables businesses to divide contacts into smaller groups based on how they interact with emails, what they buy, and other details stored about them. Standard segments update as contacts start or stop meeting the rules a user sets, such as opening a campaign without clicking a link. Users can also create fixed contact lists from CSV files or divide a larger list into random groups to compare different email versions.

How Much Does MailBluster Cost?

MailBluster pricing starts at $5/month (billed yearly) for the Pro plan, which covers unlimited leads, unlimited emails, and a developer API, plus $0.60/1,000 emails when users connect their own SMTP provider.

A free Starter plan is also available for up to 3,000 emails in total, with MailBluster branding included. Further plans include:

  • Executive - $10/month, plus $0.60/1,000 emails (billed yearly)
  • Managed - $17.00/month, for up to 10,000 emails/month(billed yearly)

Apart from the base subscription price, organizations should also consider the following estimated additional costs:

  • Integration and automation setup: Can range from $100 to $1,000+, determined by the volume of connected applications and workflow requirements
  • Custom API development: Pricing may sit between $500 and $3,000+, depending on project complexity and technical effort, API access and keys are included on Pro and Executive tiers
  • Email template customization: Can cost $100 to $500+ for creating custom, brand-aligned email templates, based on the layout quantity and complexity

The platform also offers a 14-day free trial.

Users generally praise MailBluster for its affordable, usage-based pricing, especially when managing large mailing lists. Reviewers appreciate paying based on email usage rather than contact volume, making it a cost-effective option for high-volume campaigns.

MailBluster Use Cases

Based on our evaluation of MailBluster features and user feedback, we have identified several scenarios in which the software can be the right choice:

Email Marketers Unsure Which Campaign Version Works Best

Email marketers often struggle to know which version of a campaign will get the best response, and sending an untested version to a whole list risks a weak result. MailBluster's A/B testing segments split a lead list into equal, random groups, so different versions go to each group. Marketers can compare the results first, then send the better version to the wider audience.

Marketing Teams Adjusting Emails For Different Locations

Marketing teams may have subscribers in different cities and countries, making it difficult to determine when to send emails or which regions to focus on. The platform shows where contacts are located, helping teams understand the main locations of their audience. They can use this information to choose more suitable sending times and adjust their email campaigns for different regions.

Campaign Teams Sending Generic Emails To Large Lists

Campaign teams with large contact lists often send the same generic message to everyone because creating personalized emails for individual subscribers can be difficult to manage. The software uses merge tags to personalize emails based on specific subscriber details, while its AI-driven suggestions highlight ways to improve a campaign. Teams can also set dedicated timers for specific emails.

Businesses Collecting Subscribers Without A Clear Next Step

Growth teams often find it challenging to maintain new subscribers’ attention after signing up while ensuring they can track successful conversions and measure the effectiveness of their campaigns. MailBluster solves this challenge by redirecting subscribers to custom thank-you pages or special landing pages after they confirm interest. This way, teams get the operational benefit of providing instant value and tracking conversions.

Is MailBluster Right For You?

If you want an email marketing platform for large lists at a low cost, MailBluster may be the right choice. It works for small promotions as well as large enterprise campaigns, and supports unlimited segments for organizing audiences.

For security, MailBluster keeps marketing lists on secure AWS servers in Ireland, within the European Economic Area. Only the customer, authorized employees, and the email service providers that deliver messages can access them. Payments go through Stripe over encrypted connections, and card details are not stored on MailBluster's servers.

For compliance and privacy, MailBluster follows GDPR. Users can access, correct, delete, restrict, or request a copy of their personal information. Marketing lists are not sold or shared, unless the law requires it or MailBluster is dealing with abusive or illegal activity.

MailBluster Features

Performance Dashboards

Dashboards bring recipient, delivery, open, click, bounce, unsubscribe, and complaint figures into one reporting space. Users follow campaign results as events come in, instead of waiting on traditional reports. Marketers can use them to see what is working and where changes are needed.

See How It Works
Multi-SMTP Sending

MailBluster lets businesses connect multiple supported email-sending services to the platform, including their existing accounts. This gives marketing teams greater flexibility in managing campaign delivery across different SMTP services.

See How It Works
Drag and Drop Editor

The software provides a visual email editor that enables users to build emails. They can place content blocks where they want them and add text, images, buttons, and other elements without writing code. The editor also lets users adjust colors and layouts and check a mobile preview before publishing.

See How It Works
Double Opt-In

New subscribers get a confirmation email and need to confirm they want to join before they land on a list. Users can change the sender details, tone, wording, and design of that email and its confirmation pages, either in the visual editor or in HTML. The list ends smaller but more engaged, and addresses that never confirm don't count toward the contact limit.
