Email marketing tool with pay-per-email pricing

BrevoBrevo (formerly Sendinblue) is the primary mainstream marketing email platform that prices its plans based on the number of emails you send rather than the size of your contact list.youtube.com

Most traditional email marketing tools (like MailchimpMailchimp or KlaviyoKlaviyo ) charge you more as your subscriber list grows, even if you never email half of those people. Volume-based or pay-as-you-go alternatives let you store unlimited or very large numbers of contacts and only pay for the message volume you dispatch.help.brevo.com+2

Top Email Tools Based on Send Volume

Breakdown of Top Options

1. Brevo

• How pricing works: Unlike competitors, Brevo allows unlimited contacts on most of its plans and charges you strictly based on how many total emails you send per month (e.g., 5,000 sends, 20,000 sends, etc.).
• Key features: Drag-and-drop email builder, marketing automation, SMS marketing, WhatsApp campaigns, and a built-in CRM.
• Free tier: Includes up to 300 emails per day with unlimited contacts.brevo.com+1

2. Postmark / MailerSend

• How pricing works: These services are built around raw delivery infrastructure. They do not care how many subscribers you have stored in a database; you pay for the exact number of message blocks or pre-bought credits you transmit.reddit.com
• Key features: Blazing-fast delivery speeds, deep analytics, and API/webhook integration.
• Caveat: These lean more toward developer-friendly or transactional senders, though they support broadcast-style marketing if you design your own templates or use a compatible frontend.

3. GetResponse (Pay-As-You-Go Credits)

• How pricing works: In addition to standard monthly subscriber tiers, GetResponse offers a pay-as-you-go credit model where you buy a bulk bundle of email sends upfront to use whenever you want without a recurring monthly subscriber lock-in.
• Key features: Full landing page builder, autoresponders, funnels, and webinar hosting.reddit.com

If you can share how many emails you send per month and whether you need features like visual automation or e-commerce tracking , I can recommend the exact tier or platform that fits best.

If you want a marketing email platform that charges based on emails sent rather than the number of subscribers you have, there are several good options. That pricing model is especially useful if you have a large contact list but only send campaigns occasionally.

Here are the strongest matches I found, including options with email builders, campaign analytics, and automation.

Quick price comparison

Prices are based on published pricing pages checked in October 2026. Features and plan terms may change.marketingpro.email+3

My recommendation: Start with Email Marketing Pro if you want a true pay-as-you-go service with no monthly fee. Choose day3 if you prefer a low-cost monthly plan with a defined sending allowance.

One important distinction: day3 is more focused on straightforward campaigns and product updates, while Email Marketing Pro advertises a visual email builder and more conventional marketing campaign features.

Let me narrow it down

One question: How many subscribers do you have, and roughly how many emails do you send per month?

For example, 20,000 subscribers and one campaign per month means 20,000 sends. I can compare the actual cost and help you find the best fit for your list size and sending frequency.

Amazon Simple Email Service (Amazon SES) paired with a self-hosted or lightweight frontend manager like Sendy , or true pay-as-you-go credit systems from providers like Amazon SES, Mailgun Flex , or Brevo/Mailersend let you store an unlimited number of contacts and only pay for the exact volume of emails you transmit.reddit.com

Traditional email marketing platforms charge a monthly subscription based on your total subscriber count (even if you only email them once a year). If you want to pay strictly per message sent, consider these top alternatives:

Top Pay-As-You-Go / Pay-Per-Send Options

• Amazon SES (Simple Email Service) + Sendy
  • How it works: Amazon SES charges $0.10 per 1,000 emails you send. You can store hundreds of thousands of subscribers for fractions of a penny. Using Sendy (a low-cost, one-time-fee self-hosted newsletter app) gives you a clean dashboard to manage lists and campaigns on top of SES.
  • Best for: Cost-minimalists who don't mind a little technical setup.reddit.com
• Mailgun Flex
  • How it works: Designed as a pay-as-you-go tier where you do not pay a monthly recurring base fee. You are billed incrementally based on the number of emails dispatched.
  • Best for: Developers or marketers who want a clean API and flexible transactional or bulk messaging.reddit.com
• Brevo (formerly Sendinblue) or MailerSend
  • How it works: These platforms offer standard monthly plans, but they also allow you to purchase pre-paid email credit packs that do not expire monthly. You keep your entire contact list stored for free or cheap, and only burn through credits when you hit send.
  • Best for: Users who want a ready-made drag-and-drop builder without configuring raw cloud infrastructure.reddit.com
• Elastic Email
  • How it works: Features explicit pay-as-you-go pricing starting at low baseline rates per thousand emails with zero charges for inactive stored contacts.
  • Best for: Straightforward bulk and marketing email campaigns with flexible volume pricing.quora.com

Quick Comparison of Pay-Per-Send Models

If you'd like to narrow this down, let me know:

• How many total subscribers are on your list?
• How often do you plan to send emails (e.g., once a month, weekly)?
• Do you prefer a visual drag-and-drop builder or are you comfortable with a simple/technical setup?

What you’re looking for is usually called pay-as-you-go email marketing or pay-per-email sending. Instead of paying a monthly fee based on how many subscribers you have, you pay based on the number of messages you actually send.

There’s one important distinction: some services are designed for newsletters and marketing campaigns, while others are email-delivery infrastructure that takes a little more setup.

Best options to consider

3. Mailgun

Mailgun is another option if you want to send email without paying based on subscriber count. However, its standard plans use monthly allowances and charge for additional sending, so it is not strictly pay-only-for-what-you-send.www.mailgun.com+1

My recommendation

• If you want to create and send newsletters yourself: Start with Brevo's prepaid credits.
• If you want the lowest possible cost per message: Look at Amazon SES.
• If you want email delivery for an application or website: Consider Mailgun.

Individual emails to customers, such as receipts or updates

Occasional personal or business emails
