Cheapest Email Marketing Software That Still Gets Results

The cheapest email marketing software that still gets results depends on your list size, sending volume, and the automations you need — but you can absolutely run a profitable email channel for under $20/month. Tools like Brevo (free up to 300 emails/day), AWeber (free up to 500 subscribers), and GetResponse ($19/month) all deliver real deliverability, automation, and analytics without a bloated price tag.

Why Price Isn’t the Only Number That Matters

Paying $0/month for a tool that lands in spam isn’t a deal — it’s a tax on your time. Before picking the cheapest option, check three numbers:

• Deliverability rate: Does the tool land in the inbox?
• Subscriber cap on free/entry tiers: Some tools charge you before you hit 500 subscribers.
• Automation depth: Can you send a welcome sequence, tag subscribers, and trigger emails based on behavior?

A tool that scores well on all three at a low price is the actual bargain. The ones below do exactly that.

The Cheapest Email Marketing Software That Still Gets Results: 6 Options Compared

Prices above reflect entry-level plans as of mid-2025. Always verify current pricing on each tool’s official site before subscribing.

Brevo — Best for Senders Who Need Volume Without the Bill

Brevo charges by emails sent, not by subscriber count. That pricing model alone puts it ahead of most competitors for lists that are large but infrequently emailed.

The free plan lets you store unlimited contacts and send 300 emails per day (roughly 9,000/month). The $9/month Starter plan removes the daily limit and unlocks basic reporting. At $18/month, you get A/B testing and send-time optimization.

A real workflow example: A blogger with 3,000 subscribers who sends one newsletter per week (about 12,000 emails/month) can use Brevo’s Starter plan at $9/month. The same list on AWeber’s Plus plan would run $30/month.

Watch out for: Brevo’s automation builder on the free tier is limited to one active workflow. If you need multi-step sequences from day one, you’ll need the Business plan ($18/month).

AWeber — Best Free Plan for New Bloggers Under 500 Subscribers

AWeber’s free tier is genuinely functional, not artificially crippled. You get email broadcasts, autoresponders, landing pages, and web push notifications — all at $0 for up to 500 subscribers.

The Lite plan at $15/month pushes that cap up and adds split testing. The Plus plan at $30/month unlocks behavioral automation and advanced segmentation.

AWeber has been around since 1998 [verify], which means its deliverability infrastructure is battle-tested. The RSS-to-email feature automatically sends new blog posts to your list — useful for content bloggers who don’t want to manually create every campaign.

Where it falls short: The interface feels dated compared to Kit or ActiveCampaign. Tagging and segmentation on the free and Lite tiers are basic.

GetResponse — Best When You Need Funnels and Email Together

GetResponse’s free plan includes 500 contacts, a landing page builder, and signup forms. The $19/month Email Marketing plan adds autoresponders, unlimited newsletters, and basic automation.

The real value appears at the $59/month Marketing Automation tier, which includes behavioral triggers, event tracking, and webinar hosting. For someone replacing a landing page tool and an email tool, that bundle can be cheaper than paying for both separately.

Specific use case: A side-hustler selling a $97 online course can use GetResponse’s free plan to build a landing page, capture leads, and send a 5-email welcome sequence — all before spending a dollar.

GetResponse’s deliverability consistently scores in the 99%+ range in third-party tests [verify], which matters more than any feature list.

Kit (Formerly ConvertKit) — Best Free Tier for Growing Creator Audiences

Kit’s free plan is unusually generous: up to 10,000 subscribers, unlimited landing pages, and unlimited email broadcasts. That’s enough runway to build a serious list before paying anything.

The $29/month Creator plan unlocks the visual automation builder, third-party integrations, and advanced reporting. For a blogger monetizing through affiliate links and digital products, that automation builder pays for itself quickly.

What Kit does well: Subscriber tagging and segmentation are intuitive. You can tag someone who clicked a specific link and trigger a follow-up sequence automatically — without touching code.

What Kit doesn’t do cheaply: If you need a full funnel builder, course hosting, or a CRM, Kit isn’t the answer. It’s an email-first tool and prices accordingly above 1,000 subscribers.

Systeme.io — Best All-in-One Option at the Lowest Starting Price

Systeme.io’s free plan includes 2,000 contacts, 3 sales funnels, unlimited emails, and course hosting. No other tool on this list bundles that much for $0.

The $27/month Startup plan bumps the contact limit to 5,000 and unlocks 10 funnels. For a solopreneur who would otherwise pay separately for a funnel builder (ClickFunnels starts at $97/month), an email tool, and a course platform, Systeme.io’s free tier alone represents significant savings.

The honest tradeoff: Systeme.io’s email editor and automation builder are less polished than dedicated email tools like ActiveCampaign or Kit. If email is your primary channel and you need complex segmentation, a purpose-built tool will serve you better.

ActiveCampaign — Best When Cheapest Means Most Efficient Per Dollar

ActiveCampaign doesn’t have a free tier, and its Starter plan at $15/month (billed annually, up to 1,000 contacts) looks expensive next to Brevo at $9/month. But the automation depth at that price is unmatched.

You get CRM functionality, lead scoring, conditional content blocks, and hundreds of pre-built automation recipes. A blogger using ActiveCampaign to segment buyers from non-buyers, and send different sequences to each, can see measurable improvement in open rates and conversions without upgrading.

Who should not start here: If you have fewer than 300 subscribers and no automation strategy yet, ActiveCampaign is overbuilt for your current needs. Start with AWeber or Brevo and migrate later.

How to Choose the Cheapest Email Marketing Software That Still Gets Results

Run through these four questions before deciding:

1. How many subscribers do you have now? Under 500 → AWeber free or Kit free. Under 2,000 → Systeme.io free.
2. How often will you email? Daily sender → Brevo’s volume pricing wins. Weekly sender → subscriber-based pricing is fine.
3. Do you need funnels or course hosting too? Yes → Systeme.io or GetResponse. Email only → Kit or Brevo.
4. How complex is your automation? Basic welcome sequences → any tool here. Behavioral triggers, lead scoring → ActiveCampaign.

The cheapest email marketing software that still gets results is not always the one with the lowest monthly price. It’s the one that handles your actual workflow without forcing you onto a higher plan within 90 days.

Who Should Pick Which Tool

Frequently Asked Questions

What is the cheapest email marketing software that actually delivers to inboxes?

Brevo and AWeber both have strong deliverability at their lowest price points. Brevo’s free plan caps sending at 300 emails per day but doesn’t limit your contact list. AWeber’s free tier allows up to 500 contacts with solid inbox placement. Both outperform generic SMTP solutions on deliverability consistency.

Can free email marketing plans handle a real business?

Yes, within limits. Kit’s free plan supports up to 10,000 subscribers and unlimited broadcasts — enough for a meaningful content business. Systeme.io’s free plan includes funnels and course hosting. The constraints are usually automation depth and integrations, not raw sending volume.

How many emails per month do I need to send before paid plans make sense?

Most free plans cover 1,000–9,000 emails per month. Once you exceed that range or need behavioral automation (triggered sequences, link-click tagging, purchase-based segmentation), a paid plan pays for itself in efficiency. GetResponse’s $19/month Email Marketing plan is a common first upgrade.

Is Mailchimp worth considering at the budget level?

Mailchimp’s free plan caps at 500 contacts and 1,000 emails per month, and automation is limited to a single-step welcome email. At comparable paid tiers, Brevo and AWeber offer more automation for less money. Mailchimp is worth mentioning, but it’s not the strongest choice on pure value at the entry level.

Does list size affect which tool is cheapest?

Significantly. Subscriber-based pricing (AWeber, Kit, ActiveCampaign) scales with list growth, so a 10,000-contact list costs more than a 500-contact list. Email-volume pricing (Brevo) stays flat if you send less frequently, regardless of list size. Choose the model that matches how you plan to grow.

Finding the cheapest email marketing software that still gets results comes down to matching the tool’s pricing model to your growth pattern. Start on a free tier, test deliverability with a small segment, and only upgrade when the automation you need isn’t available at your current plan. The tools above all have documented paths from $0 to a fully functional email channel.
