MailBluster vs EmailOctopus

Both MailBluster and EmailOctopus provides bulk newsletter sending service via AmazonSES. They offer many identical sounding features, and up to a certain threshold they both are free.

  • Number of Subscribers
  • List Segmentation
  • Drag & Drop Email Builder
  • A/B Testing
  • Time-Warp Delivery
  • Real-Time Tracking & Reporting
  • Integration
  • Pricing

Now, let’s jump right into the nook & cranny and reach the decisive point.

Number of subscribers

MailBluster charges you nothing for your growing subscriber list. The sky’s the limit for you always when it comes to the number of subscribers. Moreover, it is probably the only newsletter sending tool in the world which does not charge you based on your number of subscribers.

Having said that, EmailOctopus has settled its pricing issue on the basis of number subscribers. It is limiting its users to 2500 subscribers. If it crosses that magic figure then the user has to upgrade the plan and buy its premium packages to manage their subscribers.

List Segmentation

MailBluster has a supercharged segmentation tool. You can target and re-target the subscribers on the basis of their activity like whether they clicked on a specific email or not, location, purchase history, and more. It will help the marketers to focus on the most potential leads and convert them gradually.

Contrarily, EmailOctopus is not providing the List Segmentation solution. Despite that EmailOctopus is presenting the Drip-feed emails to your subscribers using automation tools. The automation is based upon lists and time. The list is editable anytime and able to send emails to the listed subscriber at a scheduled time. This feature significantly affects onboarding experiences.

Drag & Drop Email Builder

MailBluster features Drag & Drop Email Builder that let users create email templates easily and simply by WYSIWYG (What You See Is What You Get) composer. Users can incorporate their pre-built HTML codes into it as it has a code editor too! There are options to create customized texts, buttons, titles, and layouts if you don’t want to write code, just drag and drop. It’s easy and fun!

On a happier note, EmailOctopus also has the feature of creating basic emails for non-coders with a simple Drag & Drop Email Builder. You can put HTML code as well into it by simply doing copy and paste.

A/B Testing

A/B testing is undoubtedly the most effective method to test, learn and maximize the output of a marketing campaign. With MailBluster you can send multiple variations of a campaign by slicing the subscribers to A/B testing slices. It will help you to get the best opens, clicks and conversion from a specific email marketing campaign.

On the other hand, EmailOctopus does not have any feature like A/B Testing.

Time-Warp Delivery

Timewrap delivery is what assures your subscribers are not getting the right email at a wrong time which generally creates an adverse effect on the email marketing campaign. For example, If you send from New York and schedule delivery for 9 am, your west coast subscribers would generally get the email at 6 am PST. Timewarp would delay sending to anyone until it’s 9 am in their time zone. Time-warp delivery can boost your conversation by several folds. It is one of the best features you can get out of MailBluster.

Although EmailOctopus is not coming up with Time-Wrap Delivery, it is allowing you to create list and set time interval to send that campaign using automation tool.

Real-Time Tracking & Report

It is the point where both MailBluster and EmailOctopus comes with a similar feature. They both allow you to see real-time reports and analytics after sending the marketing emails.

MailBluster tracks all opened, bounced, clicked and ecommerce conversions and picturise it with charts and data tables for you to understand it easily. It is quite impressive and helpful while sending out the campaigns.

Though EmailOctopus can not track ecommerce conversions, it has real-time tracking for metrics like open rates, click rates, bounce and unsubscribes.


MailBluster allows integration with popular services like Facebook, Gmail, Instagram, Google Sheets, Dropbox, etc., via Integromat, a third-party service.  Integromat is free to use up to 1,000 operations, 100 MB data transfer, and 15 minutes minimum interval per month.

MailBluster provides you with 62K emails FREE per month. After that, it costs you as low as $0.10 for per 1000 emails. Moreover, there is no monthly fees or subscriber limitation.

EmailOctopus also has a free plan for you but with some bars and limitations. For example- it will cost you $0 forever, but the number of subscribers is limited to 2500 only. If your subscriber list is growing then you must upgrade the plan. There are more limitations with the free plan like statistics won’t be available after 90 days, you have to send campaign emails only, EmailOctopus brand will be included in the email, etc.
