Our Verdict
Sender.net’s free plan is the most generous in email marketing by subscriber count: 2,500 subscribers and 15,000 emails per month with automation, popups, and landing pages included – no credit card required. For comparison, Mailchimp’s free plan covers 500 contacts; MailerLite covers 1,000. The platform isn’t as well-known or as deep on features as Mailchimp, but for early-stage businesses that want to build a list and run automated sequences before paying anything, the free plan removes every barrier to entry. The 30% recurring affiliate commission with a 60-day cookie is among the best in the email category.
Who Sender.net Is Best For
- Bootstrapped solopreneurs who need a permanent free tier supporting up to 2,500 subscribers without ever entering a credit card
- Small nonprofit organizations running donor outreach campaigns on tight budgets who need both email and SMS in one tool
- Early-stage ecommerce stores wanting automated abandoned cart and welcome sequences without paying enterprise-level monthly fees
- Content creators and bloggers growing their first newsletter who need drag-and-drop simplicity and generous sending limits from day one
- Small agencies managing multiple client lists under 2,500 subscribers each who want to avoid per-seat pricing on basic broadcast campaigns
Who Should Look Elsewhere
- Teams needing the deepest behavioral automation - ActiveCampaign or Customer.io
- E-commerce brands needing deep Shopify integration - Klaviyo or Omnisend
- Businesses that want the most widely recognized brand for credibility - Mailchimp or Constant Contact
- Teams needing an extensive third-party app ecosystem - Mailchimp's 300+ integrations lead the category
Features Breakdown
Email Campaigns
Sender’s drag-and-drop email builder has a solid template library with responsive designs for newsletters, promotions, and transactional emails. Campaign analytics cover opens, clicks, bounces, and unsubscribes with real-time tracking. Subscriber segmentation filters by custom fields, tags, engagement history, and form source. The email builder is clean and accessible without design experience – comparable in ease of use to MailerLite.
Automation
Sender’s automation builder handles welcome sequences, re-engagement campaigns, birthday emails, and behavioral triggers based on email engagement and form events. The visual workflow canvas connects triggers, conditions, and actions in a readable flow. Automation is available on the free plan – unusual for this level of subscriber capacity. For businesses that want automated follow-up sequences from day one without paying, this is meaningful.
Popups & Landing Pages
Sender includes a popup and embedded form builder for list growth, and a landing page builder for lead capture. Popups trigger based on time on page, scroll depth, and exit intent. Forms connect directly to subscriber lists and automation triggers. Landing pages are hosted on Sender’s domain or a custom domain. All three tools are included in the free plan – significantly more than Mailchimp’s free tier provides.
SMS Marketing
Standard plan and above adds SMS marketing from the same dashboard as email. SMS campaigns reach subscribers via text message. Automation can coordinate email and SMS sequences – an email followed by an SMS if no open. SMS pricing is usage-based on top of the monthly plan. For businesses that want multi-channel outreach at low cost, Sender’s email-plus-SMS combination is competitive with Brevo and Omnisend.

Frequently Asked Questions
Before You Buy — Know This
- Sender.net's free plan is legitimately useful at 2,500 subscribers. The question to evaluate is whether the platform's feature depth meets your needs as your list grows - if you'll need complex automation past 2,500 contacts, compare Brevo or MailerLite at that contact count.
- Sender branding appears in email footers on the free plan. If removing it matters to your brand, budget for Standard ($15/mo) from the point you send to real customers.
- The 60-day affiliate cookie is longer than Mailchimp's 30-day window. For email marketing comparison content, the extended cookie captures consideration cycles that often take weeks.
- Sender.net is headquartered in Lithuania. The platform is GDPR-compliant and globally available - but verify current GDPR data residency options if that's a compliance requirement for your business.
