Sender Review 2026: Free Plan, Pricing, Pros and Cons

Sender is the free email plan to pick when you need automation without paying. MailerLite's free plan has workflows but a tiny list cap, and Kit's has list size without automations; Sender has both inside its free cap, which is why small shops and side-project newsletters keep shortlisting it.

This review is for a small business or creator deciding whether Sender's free plan can carry their email for a year, and what the upgrade costs when it cannot.

It compares the free tier with EmailOctopus, MailerLite, Kit and Brevo.

The full free field is ranked in our best free email marketing software guide.

Toolradar data: Sender is joint second for user rating among the 70 email marketing tools with 20 or more reviews on Toolradar, and 20 of the 24 newsletter tools it tracks offer a free plan (November 2026).

Marketingshot data: this newsletter reached 36,000+ subscribers as of November 8, 2026, with a 32% open rate. Our own newsletters are sent on beehiiv, which is not one of the tools reviewed here.

Methodology: every limit and price below was read on the vendors' own pricing pages on November 4, 2026. Send-count examples are our arithmetic from those limits; we do not run a test lab.

Sender is an email and SMS marketing platform founded in 2012, which says more than 180,000 companies use it. It covers newsletters, automated sequences, landing pages, signup forms and popups, and transactional email, with ecommerce blocks such as abandoned cart and order summary in the editor.

The free plan is not a stripped demo. Free Forever includes the drag-and-drop, HTML and plain-text editors, 100+ premade templates, a spam check, custom DKIM settings, scheduling, personalization and 24/7 email and live chat support.

There are no daily sending limits on any plan, so a full free-plan list can go out in one send.

The free plan's real limits are three. It has one seat, so a second person needs the shared login or a paid plan. Sender adds its branding to newsletters, signup forms and popups. And A/B testing and SMS campaigns start on Standard.

For a solo founder that is often fine; for a brand that cares how its emails look, the branding is the reason to pay.

Sender's interface is available in English, Lithuanian, Polish and Spanish. If you are comparing paid email tools rather than free tiers, our email marketing for small business ranking is the better starting point.

You sign up without a card and start on Free Forever, with 14 days of Professional features switched on. The trial ends by itself and drops you back to the free plan, so there is no surprise charge, but anything built with Professional-only blocks, such as countdown timers, will need reworking.

The free plan is sized by two numbers: 2,500 subscribers and 15,000 emails a month. A weekly newsletter to a full list uses 10,000 of those emails, which leaves room for a welcome sequence and a few automations.

A daily newsletter to the same list would need 50,000 or more sends, so daily senders outgrow the free plan long before they hit the subscriber cap (our arithmetic).

Paid plans price by list size. Standard allows 12 times your subscriber tier in emails each month and Professional 24 times, so a 500-subscriber Standard plan sends up to 6,000 emails. Free accounts and Standard share an IP address; Professional plans of 20,000 subscribers and above can get a dedicated IP, which Sender sets up on request.

There is also a pay-as-you-go route. Sender sells email credits, from 5,000 emails for $29, which also removes the branding. It suits a business that emails a large list a few times a year rather than every week.

Sender's pricing page, checked on November 4, 2026, shows Standard at $9 a month and Professional at $15 a month on monthly billing for a 500-subscriber list.

Standard adds 3 seats, removes the branding, and unlocks SMS, A/B testing, unlimited templates and landing pages, and advanced ecommerce reports. Professional adds 10 seats, the countdown timer and review blocks, advanced automation and reports, and priority support. Enterprise is a custom price with unlimited emails, SSO and phone support.

The price for lists above 500 subscribers comes from a slider on the pricing page, so check the current price for your exact list size on Sender's site. Prices exclude VAT.

In early November the page also ran a limited-time Black Friday offer for first-time users on 24-month plans, 40% off Standard and 60% off Professional, with annual billing discounted for all users; treat those as promotions, not list prices.

The free tiers differ more than the paid ones. EmailOctopus Starter is also free for 2,500 subscribers but caps sends at 10,000 a month, keeps reports for only 30 days and allows 1 landing page and 1 form and its paid Pro plan is priced by list size.

MailerLite Free now stops at 250 subscribers and 2,500 emails a month, with 2 seats; Comfort starts at $12 a month.

Kit Free is the largest at up to 10,000 subscribers with unlimited broadcasts, but visual automations and sequences start on Creator, listed at $33 a month for 1,000 subscribers.

Brevo Free allows 300 emails a day, so one 2,500-person newsletter takes 9 days to go out (our arithmetic).

Stay on Sender's free plan if your list is under 2,500 people, you send weekly or less, and one person runs email. It is the strongest free plan here for anyone who needs a welcome sequence or an abandoned-cart flow, because automation is included and Kit's larger free tier leaves it out.

Upgrade to Standard when the Sender branding starts to cost you credibility or a second teammate needs a login. Move to Kit's free plan instead if your list is heading past Sender's free cap and you only send broadcasts. Pick EmailOctopus if you want the same 2,500-subscriber free tier in a plainer tool and can live with 10,000 sends and 30 days of reports.
