How much does Sender cost in 2026?
Sender.net pricing at a glance:
- Free plan: 2,500 contacts and 15,000 emails per month, with automation, segmentation and 24/7 chat support included. Real campaigns cost $0.
- Standard $7/mo: unlimited subscribers, 12x monthly send multiplier. A 10k list gets 120k sends per month.
- Professional $14/mo: same unlimited subscribers, 24x multiplier. A 10k list gets 240k sends per month.
- Enterprise: custom quote from 100k contacts, with dedicated IPs and SLAs.
- Real cost at 10,000 subscribers: roughly $35 to $65 per month depending on plan and send volume. Consistently cheaper than Mailchimp at the same list size, competitive with Brevo and MailerLite.
The 12x and 24x multiplier that changes the math
Most email marketing platforms cap you by subscriber count. Sender.net does the opposite. Paid plans give you unlimited subscribers and cap the monthly send volume as a multiplier of your list.
Standard lets you send 12 times your subscriber count per month. Professional pushes that to 24 times. In practice:
| List size | Standard (12x sends/mo) | Professional (24x sends/mo) |
|---|---|---|
| 1,000 contacts | 12,000 | 24,000 |
| 5,000 contacts | 60,000 | 120,000 |
| 10,000 contacts | 120,000 | 240,000 |
| 25,000 contacts | 300,000 | 600,000 |
| 50,000 contacts | 600,000 | 1,200,000 |
If you run heavy automation flows, resends to non-openers, or segmentation-heavy programs, Professional pays for itself fast: twice as many messages on the same list before you hit a higher volume band.
Practical example. A 10k-contact ecommerce list running: 1 weekly newsletter (10k sends), 3 abandoned cart flows (est. 15k), post-purchase sequence (est. 20k), win-back campaign (est. 20k) = 65k sends/month. Fits comfortably in Standard 120k. Add a resend-to-non-openers on the newsletter (+8k) and a monthly promo (+30k) = 103k, still within Standard. Cross 120k with a bigger promo campaign and you either upgrade to Professional or pay overages.
What you actually pay at your list size
Sender.net’s price ladder is smooth. Cost per contact drops as your list grows:
| Subscribers | Standard/mo | Professional/mo | Cost per contact (Std) |
|---|---|---|---|
| Up to 2,500 | Free | $14 | $0.000 |
| 5,000 | ~$15 | ~$29 | $0.003 |
| 10,000 | ~$35 | ~$65 | $0.0035 |
| 25,000 | ~$65 | ~$118 | $0.0026 |
| 50,000 | ~$114 | ~$208 | $0.0023 |
| 100,000 | ~$219 | ~$400 | $0.0022 |

Hidden costs to know before you buy
1. Overage billing per 1,000 extra emails
If you burn through your monthly send allowance, Sender.net does not throttle. It bills additional emails at approximately $5 per 1,000 emails on Standard, dropping to $3.50 per 1,000 on Enterprise. One aggressive resend campaign to a 10k list can add $50 to your bill without warning. Set usage alerts inside the dashboard.
2. Add-ons priced separately from the base plan
The core plan covers marketing emails only. Transactional email, SMS and dedicated IPs are billed on top:
| Add-on | Typical cost |
|---|---|
| Transactional email | $0.001 per email |
| SMS marketing | $0.015 per message |
| Dedicated IP address | $29 per month |
3. Duplicate contacts inflate your bill 20-40%
If the same email address sits in three different lists, Sender.net counts it three times toward your billable contact total. If you segment aggressively without merging, your bill inflates 20 to 40 percent above your true audience size. Consolidate into one master list and use tags or segments instead of separate lists. This is the single biggest optimization on the platform.
Free plan: real limits vs marketing pitch
The Free plan is unusually generous by 2026 standards: 2,500 contacts, 15,000 emails per month, plus automation and 24/7 chat support. That is enough to run a real newsletter, a welcome sequence and a monthly promo for a small store.
Where it breaks:
- Sender.net branding stays in the email footer.
- You cannot use a custom sending domain (bad for deliverability at scale).
- No SMS, no transactional API, no dedicated IP.
- No priority support (chat still available, but slower response outside business hours).
Realistic pattern: startups stay on Free 3 to 6 months, upgrade to Standard the first time they need to remove branding or the first month they cross 2,500 contacts.
Annual billing saves roughly 15%
Paying annually knocks about 15% off any paid plan. On a Standard 10k-contact plan that is $63 saved per year. On Professional at 50k contacts it is roughly $370 saved. Only worth committing once your usage is stable. If you are still testing product-market fit, monthly makes more sense.
Pay-as-you-go credits for irregular senders
Sender.net also sells prepaid email credits without a monthly subscription. Credits cost roughly $0.007 per email in small packs, dropping toward $0.005 in 100k+ packs. Credits expire 12 months after purchase and are not refundable.
Credits make sense when your sending is bursty (event-based, seasonal ecommerce, occasional broadcasts) and does not justify a monthly fee. If you send consistently every month, a subscription is cheaper per email.
Sender.net vs the main competitors, priced side by side
At 5,000 contacts with a moderate send volume (~30k emails/mo), here is how the pricing lands:
| Platform | Monthly at 5k contacts | Verdict on price |
|---|---|---|
| Sender.net Standard | ~$15 | Cheapest of the group with real features included |
| MailerLite Growing Business | ~$25 | Slightly more, comparable feature depth |
| Brevo Starter | ~$25 (send-based, not contacts) | Unlimited contacts model, wins if list churns |
| Moosend Pro | ~$32 | More features (landing pages, transactional), more cost |
| Mailchimp Essentials | ~$75 | 4-5x the price, mostly for brand recognition and integrations |
| Klaviyo | ~$100 | Ecommerce-specialist premium, only worth it with Shopify data flows |
Where Sender.net stops being the cheapest: past 50k contacts if you send under 12x list size per month, Brevo’s unlimited-contacts model can pull ahead. Past 100k with heavy automation, Klaviyo’s ecommerce ROI often justifies its premium.
Pricing by industry: what to expect
Nonprofits and NGOs
Sender.net offers a discount for registered nonprofits (501(c)(3) or equivalent). Apply through their support with proof of status. Typical discount: significant reduction on paid plans, not a free upgrade to Enterprise. Combined with the already-generous free tier, small nonprofits can often run for $0 up to 2,500 contacts and pay well under $10/mo up to 10k.
Ecommerce (Shopify, WooCommerce)
Native integrations exist for both. Real cost driver is automation depth: abandoned cart flows, post-purchase sequences, and win-back campaigns easily push send volume to 8-12 emails per contact per month. At 10k contacts that is 80-120k sends, which fits Standard’s 120k allowance tightly. Budget for Professional ($65/mo at 10k) if you run 5+ active flows.
Agencies with multiple clients
Sender.net does not have a dedicated agency tier. Common patterns: (a) one Standard/Professional account per client billed as pass-through, (b) one Enterprise account with sub-accounts for each client. Pass-through is simpler for under 5 clients. Enterprise makes sense at 10+ clients when you want unified billing and reporting.
SaaS with transactional + marketing needs
Sender.net’s transactional email at $0.001/email is competitive with Mailgun and cheaper than Postmark for high volumes. However, if transactional is your primary use case (over 500k/mo), dedicated transactional providers (Postmark, SES, SendGrid) offer better deliverability guarantees. Sender.net is best when marketing is primary and transactional is secondary.
Pricing history and trend
Sender.net’s pricing has been unusually stable. The Free plan expanded from 1,000 to 2,500 contacts in 2022 (net positive for users). Standard entry price has held at $7-$8 range since 2021. No aggressive price hikes like Mailchimp’s cumulative 30% increase over the same period. If you sign up in 2026, expect broadly stable pricing through 2027 barring major platform changes.
Verdict on Sender.net pricing in 2026
For SMBs sending real campaigns to lists under 50,000, Sender.net is one of the best price/feature combinations on the market. The 12x/24x send multiplier rewards teams that actually use automation, and the free plan is a working tier rather than a marketing gimmick.
Where it stops being obvious value: past 100k contacts (compare Brevo’s unlimited-contacts model or ActiveCampaign’s automation depth), and for heavy transactional sending where SendGrid, Postmark and Amazon SES are cheaper per email at scale.
Does Sender.net charge for unsubscribed contacts?
No. Unsubscribed contacts are excluded from your billable count as soon as they opt out. This is a real cost saver versus platforms that keep charging until you manually delete opted-out subscribers.
What happens if I exceed my monthly email allowance?
Sender.net bills additional emails at roughly $5 per 1,000 on Standard, dropping to $3.50 per 1,000 on Enterprise. Sends do not stop. You get real-time usage alerts inside the dashboard and can upgrade mid-cycle to avoid the surcharge.
Can I downgrade my plan anytime?
Yes, with no penalty. Billing reflects the new plan from the next cycle, so time your downgrade at the end of a billing period to avoid paying for features you will not use.
Is there a free trial for paid plans?
Sender.net’s Free plan doubles as an unlimited-duration trial for most core features. Advanced tools (dedicated IP, SMS, transactional API) require a paid plan. There is no time-limited trial to worry about.
How does Sender.net compare to Mailchimp on price?
At 5,000 contacts, Sender.net Standard costs around $15/mo versus Mailchimp Essentials at roughly $75/mo. The gap widens with list size. Mailchimp wins on the integration marketplace and template library. Sender.net wins on raw cost per contact and the send-volume multiplier.
Is there a minimum commitment or contract?
No. Monthly plans are true monthly and you can cancel or downgrade at any billing cycle. Annual billing gets a 15% discount but locks you in for 12 months.
Where is my data stored? Is Sender.net GDPR-compliant?
Sender.net is headquartered in Lithuania (EU). Data is stored in EU data centers by default, which simplifies GDPR compliance for EU-based senders. A DPA is available on request. For non-EU customers there are no cross-border restrictions.
What payment methods does Sender.net accept?
Major credit cards (Visa, Mastercard, Amex) and PayPal. No cryptocurrency, no wire transfer for standard plans. Enterprise contracts can be paid by wire.
Does the free plan include automation?
Yes, basic automation is included on Free (welcome emails, simple triggers, scheduled sequences). Advanced automation (conditional branches, multi-step behavioral flows, deep segmentation) unlocks on Professional. This is more generous than most competitors, whose free plans lock automation entirely.
