Cheapest Email Autoresponders That Still Gets Results

The cheapest email autoresponders that still gets results aren’t hard to find — but the right one depends on your list size, automation needs, and whether you’re selling, nurturing, or just staying in touch. This guide compares six credible options under $20/month (or free), so you can stop overpaying without sacrificing deliverability or features.

Why “Cheap” and “Effective” Can Coexist

Pricing in email marketing is mostly about list size, not features. Many platforms charge $8–$15/month for up to 500–1,000 subscribers and include automation, segmentation, and decent deliverability on those entry tiers.

The trap is paying a premium tool’s starting price without using even 20% of its features. A course creator with 400 subscribers and one welcome sequence doesn’t need the same stack as a SaaS company running 12-step behavioral drips.

Knowing what you actually need — broadcasts, basic sequences, or full automation — will cut your shortlist in half before you compare prices.

What to Look for Beyond the Sticker Price

Before picking based on monthly cost alone, check these four factors:

• Deliverability: A cheap tool that lands in spam is worthless. Look for platforms with published inbox placement rates or third-party audits.
• Automation depth: Can it trigger emails based on link clicks, tags, or purchases — or only on a time delay?
• List limits vs. send limits: Some tools charge by subscribers, others by emails sent per month. Know which model fits your sending cadence.
• Free-plan restrictions: Several platforms offer free tiers that remove branding or automation unless you upgrade. Read the fine print.

The Cheapest Email Autoresponders That Still Gets Results: 6 Top Picks

1. Brevo (Formerly Sendinblue) — Best for High-Volume Senders on a Tiny Budget

Brevo’s free plan allows unlimited contacts and up to 300 emails per day. The Starter plan at $25/month removes the daily cap and unlocks basic automation.

What makes Brevo unusual is its send-volume pricing model. You pay for emails sent, not subscribers stored. If you have 5,000 contacts but only email them twice a month, you may never need to leave the free tier.

The automation builder covers welcome sequences, cart abandonment (with e-commerce integrations), and tag-based triggers. It’s not as visual or powerful as ActiveCampaign, but for straightforward drips it works well.

Best for: Bloggers and small business owners with large lists but low sending frequency.

2. AWeber — Best Free Plan for Beginners Who Want Automation

AWeber’s free plan covers up to 500 subscribers and includes one email list, basic automation, and landing pages. The Pro plan starts at $12.50/month (billed annually) for up to 500 subscribers — scaling to $20/month for 501–2,500.

AWeber has been around since 1998, and its deliverability record is consistently solid. The platform’s “Smart Designer” auto-generates branded email templates from your website URL — useful when you’re starting from scratch.

One honest limitation: AWeber’s interface feels dated compared to newer tools. The automation visual builder exists but isn’t as intuitive as Kit or ActiveCampaign. If drag-and-drop workflow design matters to you, factor that in.

Best for: Complete beginners who want a proven platform with no monthly fee under 500 subscribers.

3. Kit (Formerly ConvertKit) — Best for Bloggers and Content Creators

Kit’s free plan supports up to 10,000 subscribers — one of the most generous free tiers in the space. It includes unlimited landing pages, broadcast emails, and one automation sequence.

The paid Newsletter plan starts at $25/month for up to 1,000 subscribers and adds unlimited automations, advanced segmentation, and the ability to sell digital products directly.

Kit’s tagging and segmentation model is genuinely powerful for content creators. You can tag subscribers based on what they clicked, which opt-in form they used, or which product page they visited — then trigger different sequences accordingly. That level of behavioral targeting at this price point is hard to beat.

Best for: Bloggers, newsletter writers, and course creators who prioritize segmentation and automation depth over raw email volume.

4. GetResponse — Best All-in-One Value Under $20

GetResponse’s Email Marketing plan starts at $19/month for up to 1,000 subscribers. That tier includes email marketing, autoresponders, basic automation workflows, landing pages, and website builder access.

Few tools at this price pack in a landing page builder, a webinar feature (on higher tiers), and e-commerce integrations simultaneously. For someone building a complete online presence without buying five separate tools, GetResponse offers unusual breadth.

The autoresponder feature — its original product — is clean and reliable. You can build day-based sequences quickly, and the drag-and-drop email editor is among the most polished at this price tier.

Best for: Side-hustlers and small online businesses who want email + landing pages in one subscription under $20.

5. Systeme.io — Best Free All-in-One for Funnels + Email

Systeme.io’s free plan is genuinely comprehensive: up to 2,000 contacts, unlimited emails, 3 sales funnels, 1 automation rule, and 1 membership site — all at $0/month.

The paid Startup plan is $27/month and expands to 5,000 contacts, 10 funnels, and 10 automation rules. For entrepreneurs building sales funnels alongside their email list, this pricing model removes the need for a separate funnel builder entirely.

Deliverability is the one area where Systeme.io doesn’t publish as much public data as AWeber or Kit. Anecdotal reports suggest it’s adequate for most small lists, but if inbox placement is a business-critical metric, it’s worth testing with a small segment before migrating fully.

Best for: Beginner online entrepreneurs who want funnels, email, and course hosting without paying for three separate tools.

6. ActiveCampaign — Best “Affordable” Power Tool for Growing Lists

ActiveCampaign’s Starter plan runs $15/month for up to 1,000 contacts (billed annually). That puts it in range for this list, though it’s the ceiling of the “cheap” category.

What you get at $15/month is the strongest automation engine on this list. ActiveCampaign’s visual automation builder handles conditional logic, goal tracking, CRM-lite features, and A/B split testing on automations — capabilities that competitors charge $80–$100/month to access.

The tradeoff is complexity. New users often need 2–4 hours to get comfortable with the interface. If you’re running a simple newsletter, that learning curve isn’t worth it. But if you plan to scale past 2,000 subscribers and run segmented campaigns, starting on ActiveCampaign now avoids a painful migration later.

Best for: Marketers who expect to scale quickly and want to avoid switching platforms in 12 months.

Side-by-Side Comparison

Who Should Pick Which

The cheapest email autoresponders that still gets results aren’t interchangeable — each serves a different stage and use case.

• You have zero subscribers and zero budget: Start on Kit’s free plan (up to 10,000 contacts) or AWeber’s free plan (500 contacts). Both include real automation, not just broadcasts.
• You email a large list infrequently: Brevo’s send-volume model means a 5,000-person list you email twice a month may cost you nothing.
• You’re building funnels alongside your list: Systeme.io’s free plan bundles funnels and email in one place, which delays the need for a dedicated funnel tool.
• You want everything — email, landing pages, automations — for under $20: GetResponse’s $19/month plan is the strongest all-rounder at that price.
• You’re serious about scaling: Start on ActiveCampaign’s $15/month Starter plan. The automation depth will carry you past 10,000 subscribers without a platform change.

A Note on Deliverability

The cheapest email autoresponders that still gets results all maintain acceptable deliverability — but no budget tool is immune to spam folder issues if your list hygiene is poor. Regardless of platform, clean inactive subscribers every 90 days, use a confirmed opt-in process, and authenticate your domain with SPF and DKIM records. These steps matter more than your tool choice at list sizes under 5,000.

Email deliverability research from Validity’s State of Email report consistently shows that sender reputation — driven by engagement rates and list hygiene — outweighs platform selection for most small senders.

Frequently Asked Questions

What is the cheapest email autoresponder available?

Brevo and Kit both offer free plans with meaningful features. Brevo’s free tier allows unlimited contacts with a 300-email-per-day send cap. Kit’s free plan allows up to 10,000 subscribers with one automation sequence included.

Can a cheap email autoresponder actually deliver emails to the inbox?

Yes — deliverability depends more on list hygiene, sender reputation, and domain authentication than on platform cost. AWeber and Kit, for instance, have strong deliverability track records even on their lowest-paid tiers. Clean your list regularly and set up SPF/DKIM regardless of which platform you use.

What’s the difference between an autoresponder and an email automation?

An autoresponder sends a fixed sequence of emails on a set time delay — for example, one email immediately after signup, another after 3 days, and a third after 7 days. Email automation adds conditional logic: it can branch based on what a subscriber clicked, tagged, purchased, or ignored. Most modern tools include both.

Do I need automation, or are basic autoresponders enough?

It depends on your business model. A blogger running a welcome sequence and weekly newsletter can get by with basic time-delay autoresponders. Anyone selling products, running courses, or segmenting by interest level will benefit from at least moderate automation — meaning conditional triggers based on subscriber behavior.

How many subscribers do I need before paying for an email tool?

Most platforms let you build to 500–10,000 subscribers for free. A practical rule: upgrade when you need features the free plan blocks — typically unlimited automations, A/B testing, or removing branding. Revenue from your list, not subscriber count, should drive the upgrade decision.

Finding the cheapest email autoresponders that still gets results means matching the tool to the job — not just chasing the lowest price. Start free where possible, validate your list-building process, and upgrade only when a specific missing feature is limiting your results.
