What we tested and why it matters
- Free plan allowances and daily caps — launch throughput beats raw totals in many cases.
- Native forms, landing pages, and simple automation — these let you convert traffic without extra software.

Brevo (Sendinblue): Automation and CRM on a generous contacts plan
Brevo gives you high contact capacity plus native automation and CRM to align sales and outreach. The free plan supports up to 100,000 contacts and allows 9,000 emails per month, but a 300/day cap applies. That cap means you should pace launches or stagger campaigns to avoid hitting limits.
Strengths for segmentation and trigger-based list growth
You can build behavior-based flows that fire on visits, opens, or purchases. Prebuilt templates speed setup, so you launch workflows quickly.
Segmentation is robust: split contacts by attributes and actions to send relevant messages. The bundled CRM helps you track deals and align campaigns with sales activity.
- Leverage automation workflows tied to user behavior.
- Exportable segments and reports refine targeting.
- Free plan includes branding on messages—check if that fits your voice.
- Paid tiers (from about $9) remove daily caps and expand sending capacity.
Bottom line: If you want a service with built-in CRM and solid automation on a very large contact allowance, Brevo is a practical choice. Assess the free plan’s branding and daily cap when planning launches.
MailerLite: Advanced content blocks and solid automations for creators
MailerLite pairs modular content blocks with usable automations to help you send high-quality campaigns quickly.
The free plan includes 500 subscribers and 12,000 emails per month. You get automations, landing pages, and reporting on no-cost tiers.
What makes it fast:
- Dynamic content blocks for products, videos, RSS feeds, and countdowns speed assembly of each message.
- Launch automation flows and segments on the free plan to personalize at scale without extra tools.
- Landing pages capture leads even when you don’t have a website.
- Fewer pre-made templates on free tiers, but the drag-and-drop editor and content blocks get you to send faster.
- RSS-to-email support converts blog readers into a steady newsletter audience.
Who should pick it: creators who publish often and want design flexibility. Upgrade when you need more templates or advanced features.
Sender: Big free allowances with unlimited automation workflows
Sender pairs a generous free plan with unlimited automation that scales with simple setups. You get 2,500 subscribers and 15,000 emails per month on the free plan, plus unlimited automation workflows that run native pre-built flows.
Best for simple, scalable list-building flows
Use Sender when you need utility and speed. The service includes welcome, abandoned-cart, and win-back flows you can enable in minutes.
The A/B testing inside automations helps you test subject lines and CTAs without extra tools. That raises conversion lift while you iterate.
Tradeoffs to know before you commit
The editor is basic compared to some competitors. Expect faster setup and less design polish. If complex templates and advanced design matter, plan a minor upgrade or pair Sender with a page builder.
- Capture pace: generous free allowances and templates speed sign-ups.
- Automation: unlimited workflows and solid pre-built flows included.
- Testing: A/B subject and CTA tests inside automations.
- Segmentation: move subscribers between lists automatically.
- Pricing: affordable upgrades keep scaling predictable.

EmailOctopus: Affordable scaling when your list takes off
EmailOctopus offers predictable pricing as your audience grows. The free plan gives 2,500 subscribers and 10,000 emails per month. That makes it a practical entry point when cost matters. In addition to its affordability, EmailOctopus boasts a user-friendly interface and powerful automation tools, allowing small businesses to engage their audience effectively. With its scalable options, it is frequently listed among the best email marketing platforms, making it a top choice for those looking to expand their reach without breaking the bank. As your needs evolve, EmailOctopus provides ample resources to facilitate growth and enhance your marketing strategy. Furthermore, EmailOctopus offers excellent deliverability rates, ensuring that your messages reach your audience’s inboxes rather than their spam folders. Coupled with comprehensive analytics, you can track your campaigns’ performance, making it easier to refine your strategies over time. This combination of features solidifies its position as one of the best email marketing platforms, empowering users to achieve meaningful engagement and growth.
Keep your setup lean. The editor is simple and templates help you assemble newsletters fast. Basic automations cover welcome and nurture flows but remain limited to a few workflows.
- Start cheap and stay cheap: modest upgrade tiers keep monthly fees low.
- Integrations: Zapier and a public API connect this software to tools across your stack.
- Support note: free plan users have limited support after 30 days—plan upgrades before big campaigns.
| Plan | Free subscribers | Monthly sends | Automations | Starter upgrade |
|---|---|---|---|---|
| Free plan | 2,500 | 10,000 emails | Basic workflows | $0 |
| Growth | 10,000 | 100,000 emails | Expanded | ≈ $40/month |
| Paid (higher) | Custom | Higher sends | Full automations | Scale pricing |
In short, EmailOctopus fits cost-conscious teams who want clean UX and room to scale. Plan upgrades are affordable, and the service avoids bloat while keeping essential campaign capabilities accessible.
Honorable mentions for niche needs
If your needs skew niche—store automation or creator revenue—these alternatives deserve a quick look.
Omnisend targets ecommerce teams. The free plan allows 250 contacts and 500 emails per month and includes landing pages, site tracking, automation flows, and SMS. Use it when site-level triggers and segmentation drive conversions.
Kit (ConvertKit) suits creators. It offers up to 10,000 subscribers and unlimited emails on the free plan, plus one visual automation and one sequence. Note branding and network rules on creator-focused plans.
Beehiiv supports multiple newsletters and a built-in website. The free plan includes 2,500 subscribers and unlimited emails but lacks automations. Choose it when multi-publication workflows and sponsorships matter.
Zoho is an all-in-one suite with CRM links. The free plan gives 2,000 contacts and 6,000 emails per month for up to five users. It includes templates and CRM features but has limited workflow automation on free tiers.

- Pick Kit if you sell digital goods and want generous free sends with basic automation.
- Pick Beehiiv to run multiple newsletters and host a website without third-party tooling.
- Pick Zoho if you need CRM integration and solid templates on a no-cost plan.
| Service | Free contacts | Monthly emails | Notable free features |
|---|---|---|---|
| Omnisend | 250 | 500 | Site tracking, automation, SMS |
| Kit (ConvertKit) | 10,000 | Unlimited | 1 visual automation, sequences |

Final tip: map each service’s strengths to your monetization path—stores, sponsorships, or digital goods—and confirm integration depth with your cart, CMS, and CRM before committing.
Essential list-building features you actually need
Successful capture stacks pair targeted forms with focused landing pages and clear incentives. These elements move visitors into your audience quickly and with higher quality.
Embedded and popup forms, landing pages, and page-level targeting
Use embedded forms and popups to capture interest where it happens. Place a concise form on high-traffic pages and trigger a popup on exit intent or after a short timer.
Stand up a dedicated landing page for each offer. A single goal page reduces friction and boosts conversions by focusing attention on one call to action.
Add page-level targeting to tailor forms by content or user behavior. Targeted capture wins more qualified signups in less time.
Lead magnets, A/B testing, and double opt-in
Offer clear lead magnets—guides, templates, or discounts—to raise opt-in rates. Keep forms short: email plus one qualifier usually performs best.
Run a/b testing on headlines, form fields, and CTAs to refine conversion rates. Track submission rates by source page to prioritize high-intent content.
Finally, implement double opt-in. It protects deliverability and confirms consent, which keeps your list healthy as it grows.
- Quick checklist: embedded forms + popups, landing pages, page triggers, lead magnet, double opt-in, and regular testing.
Deliverability, branding, and daily caps: Hidden limits that affect growth
Deliverability issues and daily caps are the silent throttles on many free plans. Brevo’s 300/day cap and Mailchimp’s 500/day limit can force you to stretch campaigns over multiple days. That reduces urgency and skews results.
Check these technical and practical controls before you scale. Authenticate your sending domain (SPF, DKIM). Use double opt-in and remove inactive contacts to protect sender reputation.
- Daily caps: pace sends across days to avoid hitting limits.
- Provider branding: free plan logos can reduce perceived professionalism.
- Warm up: avoid sudden volume spikes; grow sends gradually.
- Hygiene: monitor bounces and complaints; prune inactive subscribers.
- Reporting: free tiers may hide open/click details—plan testing accordingly.
Run deliverability testing across major inboxes before large launches. If caps, branding, or reporting materially harm conversion or customer trust, upgrade the plan. That often pays back in higher inbox placement and clearer analytics.
Pricing and scalability snapshot: What “free” really covers this month
Free tiers hide real limits; this snapshot shows what you can actually send this month.
Quantify capacity first. Look at subscribers and monthly sends to set realistic goals. Daily ceilings can force staggered launches or slow testing.
Quick current snapshot: GetResponse — 500 contacts/2,500 emails per month. MailerLite — 500 contacts/12,000 emails. Brevo — 100,000 contacts with 9,000 emails per month (300/day cap). Sender — 2,500 contacts/15,000 emails with unlimited automation. EmailOctopus — 2,500 contacts/10,000 emails. Beehiiv gives 2,500 contacts and unlimited sends. Zoho allows 2,000 contacts/6,000 emails. Mailchimp caps at 500 contacts/1,000 emails per month with a 500/day rule.
What to check now: which features unlock on the free plan — automation, templates, landing pages, and editor access. Note branding, reporting, and support limits; these affect conversion and troubleshooting.
- Compare subscriber caps and monthly email limits to map growth.
- Factor daily sending ceilings into campaign timing.
- Estimate upgrade timing using current growth rate and cost per 1,000 contacts or per 10,000 emails.
- Prefer software with affordable, predictable tiers and an easy migration path.
| Service | Contacts | Monthly emails | Notable free features |
|---|---|---|---|
| GetResponse | 500 | 2,500 | Landing pages, editor access |
| MailerLite | 500 | 12,000 | Automations, templates |
| Brevo | 100,000 | 9,000 (300/day) | Automation, CRM |
| Sender | 2,500 | 15,000 | Unlimited automation |
Actionable next step: track monthly performance and upgrade before you hit a hard cap. That keeps momentum and avoids rushed migrations mid-campaign.
From zero to your first 1,000 subscribers: A simple workflow
Start small and measurable. Map one high-value offer and one tight audience segment. This keeps setup time low and signals clear when you test form placement and page copy.
Capture, segment, automate, and iterate with testing
Capture: publish a focused landing page with a clear lead magnet. Add site-wide embedded forms and an exit-intent popup to catch visitors before they leave.
Segment: tag new signups by source or interest right away. Early segmentation improves targeting and reduces churn. By understanding the motivations behind each signup, businesses can tailor their communications to better meet the needs of their audience. This strategic approach can be particularly enhanced by leveraging insights from the best email marketing platforms, which offer tools for effective segmentation. As a result, companies can create personalized campaigns that resonate more deeply, leading to improved engagement and long-term customer loyalty.
Automate: set a 3–5 step welcome series that delivers value, sets expectations, and asks for a first engagement. Use simple behavioral tags (clicked topic X) to trigger personalization in future sends.
- Run a/b testing on headlines, CTAs, and form fields to lift conversions quickly.
- Send one weekly email to stay top of mind while you scale.
- Clean bounces and inactive records monthly to protect deliverability.
- Review metrics and iterate capture and content weekly; keep changes small to measure impact.
| Step | Action | Quick goal (time) |
|---|---|---|
| 1. Capture | Landing page + embedded forms + popup | Publish within 48 hours |
| 2. Segment | Tag by source/interest at signup | Immediate |
| 3. Automate | 3–5 email welcome series | Schedule over 2 weeks |
| 4. Test & iterate | A/B testing on CTAs/headlines; review weekly | 2-week test windows |
Scale what works; drop what doesn’t within two weeks. That discipline saves time and focuses growth on tactics that move the needle toward your first 1,000 subscribers.
CTAs that convert: Place them across forms, popups, and newsletters
A tight, benefit-led call to action lifts conversion across pages, forms, and messages. Make the promise specific. “Get the 5-step checklist” beats a vague ask every time.
Use clear visual contrast and white space to guide attention. Put the primary CTA above the fold on landing pages and in timed popups. Reiterate the CTA mid-newsletter and again in the PS for skimmers.
Keep friction low. Ask for the minimum fields. Short copy and large tap targets improve mobile conversions.
- Align CTA language with your lead magnet or offer.
- Test microcopy, button color, and placement to gain steady lifts.
- Use urgency ethically — timers and deadlines raise response without harming trust.
- Reuse winning variants as the new control in your editor and templates.
| Element | Action | Why it works | Expected lift |
|---|---|---|---|
| Button copy | Benefit-first phrase | Clarifies value instantly | 5–15% |
| Placement | Above fold + popup | Increases visibility | 10–20% |
| Urgency | Countdown timers | Creates immediate action | 8–12% |
| Design | Contrast + whitespace | Improves click focus | 4–10% |
Test iteratively. Run small A/B tests and drop losing variants quickly. Scale winners across templates and newsletters to compound gains.
