What is the Cheapest Email Service?

1. SendX

SendX is one of the most affordable autoresponders out there. Their pricing structure is based on the number of subscribers in your list and then you can send unlimited emails. Your pricing plan changes only when you grow your subscribers. You can access all the features at all pricing plans.


SendX paid pricing starts for as low as $7.49/month (when billed annually) and $9.99/month (billed monthly). 

Before you commit, you can take a 14-day free trial and get access to all the features.

Now, don’t assume that if it’s the cheapest it’s skimming on the features. 


This autoresponder gives you all the critical features you need to put your marketing on autopilot. You can always edit automation rules in the future to add or update either triggers or actions. You can also categorize different types of users in different user groups or lists & trigger emails based on their behavior. 


All this is made possible while maintaining a simple user experience & intuitive interface. I think that gives it an edge over all the other autoresponders that lack the ease-of-use. 


2. SendPulse

With Sendpulse, you can send Subscriber and date-based, as well as trigger-based (email opens, clicks, email not opened). Advanced automation is available on higher plans.


They offer monthly, 6-months, and yearly pricing. Their pricing is based on the number of subscribers.


It starts from $9.85/month for 2,500 subscribers and goes up to $5,600/month for 500,000 subscribers.

They also have a pay as you go plan. For autoresponders, you will have to take an estimate if you choose this plan as you won’t know the exact number of emails that might be sent out. This is good if your business is seasonal. 


Pay As You Go plan starts from $32/10,000 emails & is valid for 12 months after purchase


3. Mailchimp 

Mailchimp suggests using their automation but even their legacy autoresponder is powerful. 


It includes essential autoresponders (Welcome email, order notifications, abandoned cart, RSS, etc), as well as more advanced options (e.g. e-commerce, tag-based). The main drawback is that their autoresponder editor isn’t the easiest to use.


If one of your autoresponders uses a layout or includes content you like, you can save it as a template to reuse with other campaigns and automation.

One thing you will observe as we go through these pricing plans is that Mailchimp's pricing starts off cheap but gets really costly as your audience increases. 

You can sign up for a forever free plan but that only allows you to access only a few features. Forever Free plan: $0, 2000 contacts, 10K emails 

The rest of the plans are based on a combination of features you use and the number of contacts you have. For 500 contacts, this would be the pricing: 


Essential plan: $10/mo, 500K emails 

Standard Plan: $15/mo 1.2M emails

Premium Plan: $314mo, 3M+ emails


Then the pricing increases as your list count increases. And remember, the Mailchimp counts subscribers & unsubscribers to calculate the list count.

Mailchimp is actually one of the most expensive newsletters tools out there for small-to-medium businesses. If you are looking for a budget-friendly solution we’d encourage you to try SendX. 

You’ll be joining many other former Mailchimp users who’ve shifted to SendX and never looked back.


4. AWeber

Aweber built one of the first well-known autoresponder software, and it's still widely used and loved. 

AWeber’s user experience is not so smooth but autoresponder capabilities are decent.

Using their automation feature you can use clickthrough and tagging to decide what should be sent to whom and when.



AWeber has only one price plan that changes based on the number of subscribers. 

You can choose from monthly, quarterly, and annual billing systems. 


The lowest monthly plan is $19/mo for up to 500 subscribers. You save 14% if you choose quarterly & 14.9% if you choose the annual plan.
