Sender Review 2026: The Generous Free Plan Nobody Talks About

Sender does not get mentioned as often as Mailchimp, MailerLite, or Brevo, but on paper it is competing very effectively. Its free plan — 2,500 subscribers and 15,000 emails per month, permanently — is more generous than almost every competitor at zero cost. It has a 97% deliverability rate, includes automation on all plans, and starts at $10/month when you need to scale.

The honest question is whether it trades features for that pricing, and where the ceilings are. This review covers what Sender does well, where it falls short, and who should use it.

Pricing

Free Forever: 2,500 subscribers, 15,000 emails/month. Includes automation, transactional emails, forms, and basic reporting. No trial period — this is a permanent free tier.

Standard: $10/month for up to 2,500 subscribers. Removes Sender branding, adds priority support, increases email send limits, and unlocks additional automation triggers.

Professional: $35/month for up to 2,500 subscribers. Adds dedicated IP, advanced analytics, and custom reporting.

Enterprise: Custom pricing for lists above 100,000 subscribers.

The free plan is the headline feature here. Most competitors start restricting at 250–500 contacts (Mailchimp caps at 250 contacts free). Sender’s 2,500-contact free tier means a small business or creator with a few hundred subscribers can run legitimate email marketing — automation included — without spending anything.

Deliverability

Sender reports a 97% deliverability rate, on par with MailerLite and above Mailchimp’s 96%. This is not a situation where the free plan comes with deliverability compromises — senders report consistent inbox placement across major providers including Gmail, Outlook, and Apple Mail.

The platform uses shared IP pools on free and Standard plans, with a dedicated IP available on Professional. For most small lists, shared infrastructure performs well. If you’re running high-volume transactional sends or have a domain reputation concern, the dedicated IP on Professional is worth the cost.

Automation

Sender includes automation on the free plan, which is unusual. You can build standard welcome sequences, tag-based drip campaigns, and form-triggered onboarding flows at no cost. The automation builder covers: email sequences, delays, conditions based on subscriber tags, and actions based on link clicks or opens.

What Sender lacks is A/B testing. There is no built-in split testing on any plan. If you run systematic tests on subject lines, content, or send times, this is a real gap. MailerLite and Mailchimp both include A/B testing on their paid plans. For data-oriented marketers, this is the most significant missing feature.

Templates and Editor

Sender includes a drag-and-drop editor with a template library. Templates are functional — enough variety to cover newsletters, promotions, and onboarding sequences — but the library is smaller than AWeber (600+) or Mailchimp. The editor is reasonably fast to use and produces clean, readable emails.

If you work from custom HTML, Sender supports pasting and editing raw code. The rendering preview across email clients works reliably.

Integrations

Sender has roughly 50 native integrations. This is the narrowest integration library of any major platform in this price range. The key connections are there: Shopify, WooCommerce, WordPress, and Zapier (which extends coverage considerably). If your marketing stack runs on unusual tools or enterprise software, check the integration list carefully before committing.

Who Sender Is Right For

New lists with 0–2,500 subscribers: The free plan gives you a legitimate email marketing setup with no monthly cost. For a creator just starting to build an audience, or a small business with a few hundred subscribers, Sender’s free tier is hard to beat.

Budget-conscious growing businesses: At $10/month, Sender’s Standard plan is cost-effective for lists up to 2,500 subscribers. If you don’t need A/B testing and your integrations are covered by Zapier or the native library, the price-to-capability ratio is excellent.

Transactional email senders: Sender handles transactional emails on all plans, including the free tier. For small SaaS or e-commerce companies that need both marketing and transactional sends, the combined capability at a low price point is useful.

Who Sender Is Not Right For

If A/B testing is part of your regular workflow, Sender’s omission here is a real problem. If you need an extensive native integration library, Sender’s 50 integrations will likely require Zapier workarounds. If you’re running a list above 10,000 subscribers, compare Sender’s Professional pricing against Moosend and MailerLite at the same tier — the gap narrows as your list grows.

Bottom Line

Sender earns its high rating. The 2,500-subscriber permanent free plan is genuinely useful — not a limited trial or a heavily restricted “starter” tier. Deliverability is strong. Automation works on the free plan. Pricing is competitive at every paid tier.

The gaps (no A/B testing, limited integrations) are real enough to push some users toward MailerLite or Mailchimp. But for a business that does not rely on split testing and has standard integration needs, Sender offers better value than most alternatives in its price range.
