02The Shortlist
Brevo
From$8.08/moValue score4.7/5
Why it’s here: One low-cost account for marketing email, transactional email and SMS.
Brevo, formerly Sendinblue, combines email campaigns with SMS, WhatsApp, transactional email and a light CRM. Its pricing is based on how many emails you send, not on how many contacts you store, which favors large lists that are mailed occasionally. The free plan caps daily sends instead of list size.
- Best for
- SMBs that want email, SMS, and transactional messaging in one tool
- Pricing
- Starter plan, billed annually ($9 billed monthly), from 5,000 emails per month. Free plan: 300 emails a day.
- Key features
- Email campaigns and automation, Transactional email, SMS marketing
Where it falls short: Templates and reporting are plainer than Mailchimp’s, and the free plan’s daily cap limits how many people you can reach at once.
MailerLite
From$10.80/moValue score4.6/5
Why it’s here: Cheap, quick to set up and good enough until marketing becomes someone’s full-time job.
MailerLite is a simple, inexpensive email tool with a clean editor. Newsletters, landing pages, forms and straightforward automations are all there, and the free plan is usable. It leaves out the heavier features, which keeps both the interface and the bill small.
- Best for
- Small businesses and creators that want value and simplicity
- Pricing
- Comfort plan, billed annually ($12 billed monthly), 500 subscribers at this price. Free plan: up to 250 subscribers.
- Key features
- Newsletter builder, Automation workflows, Landing pages and websites
Where it falls short: Automation, reporting and integrations are lighter than in the bigger platforms.
Mailchimp
From$13/moValue score4.5/5
Why it’s here: Familiar to almost any hire, though the price grows with the list.
Mailchimp is the email tool most small businesses try first. It covers campaigns, templates, basic automation, landing pages and forms, and connects to almost everything. It is a generalist: good at getting a newsletter out, less convincing once you need advanced automation, and priced by the size of your audience.
- Best for
- SMBs that want a familiar general-purpose email platform
- Pricing
- Essentials plan, billed monthly, 500 contacts at this price. Free plan: 250 contacts and 500 sends a month.
- Key features
- Email campaigns and templates, Audience segmentation, Marketing automation journeys
Where it falls short: The price rises with every contact you add, the free plan is small, and automation is shallower than in specialist tools.
ActiveCampaign
From$15/moValue score4.2/5
Why it’s here: The choice once lifecycle automation becomes a growth channel.
ActiveCampaign is an automation tool that also sends email. Its visual builder handles branching logic, lead scoring, site tracking and conditional content, and a sales CRM can be added on. It asks for more learning than its simpler rivals and repays it for businesses whose marketing depends on timing and behavior.
- Best for
- Businesses that prioritize automation and segmentation
- Pricing
- Starter plan, billed annually ($19 billed monthly), 1,000 contacts at this price.
- Key features
- Advanced automations, Segmentation and personalization, Built-in CRM
Where it falls short: There is no free plan, the learning curve is real, and the cost climbs with both contacts and tier.
ConvertKit
From$33/moValue score4.1/5
Why it’s here: Fits founder-led companies that grow through content and a newsletter.
ConvertKit, now called Kit, is email marketing for creators: writers, podcasters, course sellers and newsletter operators. Subscribers are organized with tags instead of lists, automations are drawn as simple visual flows, and you can sell digital products and paid subscriptions from the same account. Emails are plain and text-first by intent.
- Best for
- Creators and newsletter businesses focused on audience building
- Pricing
- Creator plan, billed annually ($39 billed monthly), 1,000 subscribers at this price. Free plan: up to 10,000 subscribers.
- Key features
- Visual automations, Landing pages and forms, Creator commerce tools
Where it falls short: Design options and reporting are limited, and it is not built for stores or sales teams.
GetResponse
From$15.58/moValue score4.3/5
Why it’s here: Email plus landing pages and funnels without extra subscriptions.
GetResponse packs a lot around its email tool: automation, landing pages, sign-up funnels, webinars and a website builder. It suits marketers who want one subscription for lead generation and follow-up. Breadth is the appeal, and no single part is the best in its class.
- Best for
- Marketers who want email plus funnels and webinars
- Pricing
- Starter plan, billed annually ($19 billed monthly), 1,000 contacts at this price. Free plan: up to 500 contacts.
- Key features
- Email campaigns and autoresponders, Marketing automation, Conversion funnels
Where it falls short: The interface is crowded, and the more advanced automation and webinar features need the higher tiers.
Beehiiv
From$49/moValue score4.1/5
Why it’s here: For startups whose product is the newsletter, or whose growth runs through one.
Beehiiv is a newsletter platform, not a general email marketing tool. It bundles a website, a referral program, recommendations between newsletters, an ad network and paid subscriptions, all aimed at publishers who want to grow and earn from a list. Automation and ecommerce features are minimal because that is not what it is for.
- Best for
- Publishers and creators growing newsletter audiences
- Pricing
- Lite plan, billed annually, 1,000 subscribers at this price. Free plan: up to 2,500 subscribers.
- Key features
- Newsletter publishing, Referral and recommendation tools, Ad network and monetization
Where it falls short: It is not suited to stores or sales-driven marketing, and the paid plans cost more than basic email tools.
