Quick answer

Sender is my pick for most small lists. Its free plan holds 2,500 subscribers, where Selzy's free plan stops at 100 contacts, and Sender Standard includes 3 seats while Selzy doesn't publish a seat count on any plan. Selzy wins one case on price: at 5,000 contacts Selzy Lite is $30/month billed monthly against Sender Standard at $39/month billed monthly, with unlimited emails. Both yearly discounts are first-year offers: Selzy sells 30% off for the first year and doesn't publish its renewal rate, and Sender gives 30% off the first year, then renews at the monthly price. Prices verified 1 Oct 2026.

Across the three setups below: Sender in 2 of 3 scenarios.

Which one fits you?

  1. Solo marketer or small business, a list just past the free tier

    Sender logo

    Sender

    My pick

    $0/mo billed annually

    A 500-subscriber list fits Sender's free plan, which covers up to 2,500 subscribers, so it costs $0/month billed monthly. Selzy's free plan stops at 100 contacts, so the same list needs Lite at $7.50/month billed monthly, or $5.25/month billed annually for the first year.

    Why this pick, and when to skip it

    Skip it if you want unlimited emails on a paid plan. Sender's free plan caps sends at 15,000 emails a month, while Selzy Lite sends an unlimited number.

  2. Growing list, sending regularly

    Selzy logo

    Selzy

    My pick

    $21/mo billed annually

    At 5,000 contacts Selzy Lite is $30/month billed monthly, against Sender Standard at $39/month billed monthly. On yearly billing Selzy Lite is $21/month billed annually for the first year. Sender's annual figure, $39/month billed annually, is the renewal rate from year two, and new customers get 30% off in the first year. Selzy sends unlimited emails at this size.

    Why this pick, and when to skip it

    Selzy is cheaper on monthly billing, where both prices are standing. I'd pick it on that basis, and re-check the yearly rate at renewal.

    Skip it if you want the email quality checker (anti-spam, size and authentication checks). It is only on Selzy Standard, which costs more than Lite at this list size. You may also prefer Sender if you want to know the renewal price: Selzy doesn't publish its yearly renewal rate.

  3. Small team managing one list together

    Sender logo

    Sender

    My pick

    $15/mo billed annually

    For three people on a 1,000-contact list, Sender Standard includes 3 seats and costs $15/month billed monthly, or $15/month billed annually at renewal. Selzy doesn't publish how many users Free, Lite or Standard include, so there is no published Selzy price for a three-person team.

    Why this pick, and when to skip it

    Skip it if Selzy confirms in writing that Lite covers three users. On list size alone Selzy Lite would then compete at 1,000 contacts.

How are Selzy and Sender really different?

  • Free plan

    Selzy
    100 contacts and 1,000 emails a month, with a Selzy logo in the footer, plus a 14-day trial of the paid plans.
    Sender
    Up to 2,500 subscribers and 15,000 emails a month, with email automation and no card. No trial of the paid plans.

    A list of 500 stays free on Sender and pays Lite on Selzy. Selzy's trial is the only way either lets you test the paid features.

  • How you pay as the list grows

    Selzy
    By unique contacts emailed in a month, with unlimited emails on Lite and Standard. Prepaid per-email packages are the other model.
    Sender
    By subscriber count, with a monthly send cap that scales with the list: 12x subscribers on Standard, 24x subscribers on Professional.

    If you mail a lot, Selzy's unlimited sends matter. If you mail once or twice a month, the caps on Sender rarely bite.

  • Yearly discount terms

    Selzy
    30% off, sold as an offer for the first 12 months. Selzy doesn't publish the renewal rate.
    Sender
    30% off the first year for new customers. Renewal is the same per month as monthly billing.

    Neither yearly price is a lasting one. With Sender you know the number you renew at. With Selzy you have to ask.

  • Team seats

    Selzy
    Not published for any plan.
    Sender
    1 on Free, 3 on Standard, 10 on Professional.

    A team can plan around Sender's numbers. With Selzy you have to ask first.

  • Deliverability checks

    Selzy
    An email quality checker (anti-spam tips, size check, SPF, DKIM and DMARC check) on Standard and Enterprise only.
    Sender
    Sender's pricing page doesn't list a deliverability checker by tier.

    If you want a built-in check before each send, Selzy Standard is where it sits, and it costs more than Lite.

How I calculated this

For each tool I price every current plan plus the add-ons a setup needs, from the vendor's published prices only, and take the cheapest. Monthly and annual billing are priced separately. When a limit or price isn't published, the tool shows as not fitting instead of a guess.

  • Solo marketer or small business, a list just past the free tier: A list of about 500 contacts, just past the free tiers most vendors offer. One login. Tools priced by emails sent are costed at three mailings per subscriber a month.
  • Growing list, sending regularly: A list of 5,000 contacts, sending regularly. One login. Tools priced by emails sent are costed at three mailings per subscriber a month.
  • Small team managing one list together: Three people logging in to the same 1,000-contact list. Seats, not list size, are the deciding limit.

Who should pick Selzy, and who should pick Sender?

Selzy

Desk research
  • Best for growing lists sending regularly

Selzy charges for contact list size and lets you send as many emails as you like, starting at $7.50/month billed monthly on Lite (or $5.25/month billed annually) at its entry contact band. The free plan covers 100 contacts and 1,000 emails a month, and every plan, including Free, comes with round-the-clock support. The yearly price is a 30% first-year offer, and Selzy doesn't state the renewal rate.

Best for: Small lists that mail often: unlimited sends on Lite and Standard, with round-the-clock support and automation on every plan, including the free one.

Strengths

  • A free plan with 100 contacts, 1,000 emails a month and automation included, plus a 14-day trial.
  • Lite and Standard send unlimited emails, so cost follows list size rather than send volume. Standard is $15/month billed monthly at the entry band, or $10.50/month billed annually.
  • Yearly billing takes 30% off, and Standard adds the email quality checker (anti-spam, size and authentication checks).

Limits

  • The free plan stops at 100 contacts and adds a Selzy logo to every email.
  • Lite and Standard price by unique contacts emailed in a month, and Lite counts contacts you delete until the billing period ends, so swapping out a list does not free up room.
  • No team-seat count is published, and CRM and e-commerce integrations are a separate paid add-on, with the WordPress plugin and API-based connections free.

Skip it if you need a larger free plan, a published team-seat count, or a flat price that stays put as the list grows, since Lite and Standard step up with every contact band.

Sender

Desk research
  • Best for solo marketers and small businesses
  • Best for small teams sharing one account

Sender's Free Forever plan covers 2,500 subscribers and 15,000 emails a month with no credit card, a generous free tier for a list-priced ESP. Paid plans start at $9/month billed monthly at 500 subscribers, with a published price at every list size up to 200,000 subscribers. Annual billing carries a first-year new-customer discount ($6.30/month billed annually at 500 subscribers), then renews at $9/month billed annually. Prices climb fast with list size.

Best for: Small stores and solo lists under 2,500 subscribers that want real automation for free, or a cheap paid plan while the list stays small. The free plan's automation and segmentation match what some competitors charge for.

Strengths

  • Free plan covers 2,500 subscribers with automation and segmentation included, not gated behind a paid tier.
  • Entry paid pricing is cheap at small list sizes: Standard is $9/month billed monthly at 500 subscribers, or $6.30/month billed annually in the first year on annual billing.
  • An official MCP server (mcp.sender.net) with 40+ tools for managing subscribers, segments, and campaign drafts, though by design it cannot send or activate a campaign.

Limits

  • The first-year annual price ($6.30/month billed annually for Standard, $10.50/month billed annually for Professional at 500 subscribers) includes a new-customer discount; renewal is $9/month billed annually for Standard and $15/month billed annually for Professional, the same as monthly billing, and that is the number to budget against past year one.
  • No published money-back guarantee, refund policy, or cancellation terms anywhere on the pricing page.
  • No free trial for the paid plans; the free-forever tier is the only no-card option, so there's no way to trial Standard or Professional features before paying.

Skip it if you want a standing annual-billing discount: after the first year, annual billing costs the same per month as monthly billing.

Switching between Selzy and Sender

Neither vendor documents a migration service, so plan on exporting your contacts as a file, re-importing them, and rebuilding templates and automations by hand in either direction. Sender's free plan up to 2,500 subscribers and Selzy's 14-day trial let you rehearse the move before paying. One Selzy detail to know before you import: its list-based plans count every unique contact you email in a month, so clean the list before the first send.

What would change my pick?

  • Selzy publishing a seat count. If Lite covers three people, Selzy would compete in the team scenario, since it is cheaper at some list sizes.
  • Selzy publishing its yearly renewal rate. A renewal close to the monthly price would remove its first-year edge on yearly billing.
  • Sender adding a standing annual discount past the first year, or raising its free plan's send cap.
  • A price change on either side. The scenario picks recalculate from the published numbers.

Selzy vs Sender: questions people ask

Which is cheaper, Selzy or Sender?

It depends on list size. A 500-subscriber list is free on Sender and $7.50/month billed monthly on Selzy Lite. At 5,000 contacts Selzy Lite is $30/month billed monthly against Sender Standard at $39/month billed monthly. Selzy is cheaper at the larger size and Sender at the smaller one.

Is Selzy or Sender free?

Both have a free plan. Sender's covers up to 2,500 subscribers and 15,000 emails a month. Selzy's covers 100 contacts and 1,000 emails a month, with a Selzy logo in your emails.

Does Selzy's yearly discount last?

Selzy sells it as 30% off for the first 12 months and doesn't publish the renewal rate. Sender's 30% off also covers only the first year, and Sender Standard then renews at $9/month billed annually at 500 subscribers, the same as monthly billing.

Does Selzy work for a team of three?

Maybe, but Selzy doesn't publish how many users its plans include, so ask its support before you commit a team to it. Sender Standard includes 3 seats and costs $15/month billed monthly at 1,000 contacts.

Does Selzy charge by emails sent or by list size?

By list size on Lite and Standard, with unlimited emails. Selzy counts each unique contact you email within a month. If you send rarely to a large list, it also sells prepaid per-email packages with no contact limit. Sender is priced by subscriber count with a monthly send cap.

Can I try the paid features before paying?

On Selzy, yes: a 14-day trial with caps on emails and contacts, and Selzy doesn't say whether it needs a card. Sender offers no trial of Standard or Professional, so you try the free plan and then commit.
