Sender looks cheap on the surface, but the bill quietly climbs as your subscriber list grows. Here is what it really costs and where the value falls short.
by Alkan Balkaya · Last updated: 2026-05-08Sender pricing centers on a generous free plan and paid tiers priced by subscriber count, so it stays affordable for small lists but climbs steadily as your contacts grow. For beginners it is one of the cheapest entry points. For scaling senders, add-ons and per-contact charges erode that early advantage.
The tricky part is not the headline price. It is how that price moves once your list passes a few thousand subscribers, plus the extras that do not show up in the first quote. Below is a clear, buyer-focused breakdown of what Sender costs, where the value weakens, and how a list-based alternative like Mailsoftly compares.

Key Takeaways
Sender uses a freemium model: a no-cost plan for small lists, then paid Standard and Professional tiers priced by how many subscribers you store. There is also pay-as-you-go email credit option for occasional senders. Pricing in this article reflects publicly listed rates (as of 2026-04-15); always confirm current figures before you buy.
Because Sender adjusts paid plan cost in steps tied to your subscriber count, there is no single number that answers “how much does Sender cost.” A 1,000-contact list and a 25,000-contact list sit on very different rungs of the same ladder. For the exact current figures at each subscriber band, check the official Sender pricing page, since vendor tiers shift over time and we will not quote numbers we cannot verify.

Sender pricing scales with the number of subscribers you store, not the number you actually email. That is the core trap of contact-based pricing: a dormant contact who never opens a message costs the same as your most engaged buyer. As your list grows, your bill grows with it, even when revenue per contact is flat.
This matters because list size and engagement drift apart over time. You collect signups, run a lead magnet, import an old spreadsheet, and suddenly you are paying for thousands of contacts who rarely engage. Since email marketing consistently posts one of the highest returns in digital channels according to HubSpot’s marketing statistics, the goal is to keep cost per active subscriber low, not to pay a premium for inflated list counts.
The headline plan price rarely matches the final invoice. Sender’s true cost usually includes one or more add-ons layered on top of the base subscription, and these are the line items buyers forget to budget for.
None of these are unique to Sender, but they add up. Before committing, total your realistic monthly figure: base plan, expected list growth, branding removal if you need a clean sender identity, and any SMS or premium features. That number, not the advertised starting price, is what you should compare against alternatives.
Mailsoftly uses transparent list-based pricing with a permanent free tier and free hands-on migration, so the value gap shows up most clearly as your list grows and Sender’s add-ons stack up. The table below uses verified Mailsoftly figures alongside other common platforms so you can see where each one fits.
| Platform | Starting paid price | Free plan | Support | Best for |
|---|---|---|---|---|
| Mailsoftly | $39/mo annual (5,000 contacts) | Yes, 500 contacts | Human support, free migration | Teams wanting transparent value |
| Sender | Subscriber-based (see official page) | Yes | Email and chat | Beginners on a tight budget |
| Brevo | From $9/mo (by email volume) | Yes, 300/day | Email and chat | High-volume, low-list senders |
| Mailchimp | Essentials from $13/mo (500 contacts) | Yes, 250 contacts | Tiered by plan | Established brands |
| Constant Contact | Lite from $12/mo (500 contacts) | No (60-day trial) | Phone and chat | Event-driven growing businesses |
Mailsoftly’s free plan covers 500 contacts and 2,000 emails per month with no credit card, and paid plans move up in clear steps: Basic at $39 per month annually for 5,000 contacts, Business at $79 for 15,000, and Premium at $159 for 30,000. The difference in practice is predictability. You always know your next price band, and you get the same human support and free migration whether you are on the free tier or scaling up. You can review the full breakdown on the transparent Mailsoftly pricing page.
Sender pricing fits beginners and small senders with modest, slow-growing lists who value a strong free tier above advanced features. If you have a few hundred to a couple thousand subscribers and send occasionally, the free plan can genuinely carry you for a long time.
It fits less well once your list scales or your sending becomes core to revenue. At that point per-contact pricing, send caps, and add-ons start to matter, and the early savings shrink. Engagement also concentrates on mobile, where more than half of all opens now happen per Litmus research on email ROI and behavior, so growing senders should weigh deliverability and support quality as heavily as the monthly rate, not just the cheapest sticker price.
The fastest way to lower a Sender bill is to stop paying for contacts who do not engage. Because pricing is contact-based, list hygiene directly reduces cost. After that, the lever is choosing a plan and billing cycle that match how you actually send.
Switching is where most of the saving hides, because people tolerate an overpriced plan to avoid the hassle of moving. When migration is handled for you and the new pricing is transparent, that friction disappears and the lower bill becomes immediate rather than theoretical.

Sender really costs whatever your subscriber count and add-ons add up to, not just the advertised starting price. The free plan is genuinely free for small lists, but paid Standard and Professional tiers rise with contact count, and extras like SMS credits and branding removal push the real invoice higher. Total your expected list size plus add-ons before comparing, and confirm current figures on Sender’s official pricing page.
Yes, Sender has a free plan, and it is one of the more generous in the market. It suits beginners and small lists, though it includes Sender branding on your emails and caps monthly send volume. To remove the logo and lift sending limits you move to a paid tier. For comparison, Mailsoftly’s free plan covers 500 contacts and 2,000 emails per month with no credit card required.
No, Sender is not expensive for small lists. It is one of the cheapest ways to start, and many small senders stay on the free tier for a long time. Costs only become a concern as your subscriber count climbs and add-ons accumulate. If you expect steady growth, compare the price you will pay at a larger list size, since that is where contact-based pricing gets costly.
Sender is worth it if you are a beginner who values a strong free plan over depth and support. As you scale, alternatives with transparent list-based pricing, free migration, and human support often deliver more value at the same list size. Mailsoftly is built for that switching moment, offering predictable price bands and hands-on help moving your contacts, templates, and automations over.
