The Best Email Marketing Software Under $50 a Month

The short answer: a $50 monthly budget buys a serious email marketing tool up to about 5,000 contacts — but only on the right vendors. MailerLite Comfort costs $49 a month at 5,000 subscribers and Moosend Pro costs $48, both with automation included. Brevo Standard fits the budget too, but only if you send infrequently, because Brevo bills per email sent rather than per contact. The familiar names break the line at that size: Mailchimp Essentials is $75, GetResponse Starter is $54, AWeber Lite is about $60, and Flodesk Pro is $59 at 5,000 subscribers. Below, the table shows exactly where each tool crosses $50 — and the traps that push a plan over the line after you sign up.

Why $50 is a real budget line, not a round number

Fifty dollars a month is where small-business email budgets usually sit: high enough for a real tool with automation, low enough that the owner notices it. The reason it works as a dividing line is structural. Email vendors price on three different axes, and each axis crosses $50 at a different list size — so “under $50” is not one market, it is three different races that happen to share a finish line.

Per-contact pricing (MailerLite, Moosend, Mailchimp, GetResponse, AWeber) charges for list size. The bill climbs as the list grows, whether you send daily or monthly. On this axis, $50 buys you up to roughly 5,000 contacts on the cheapest tools and only about 2,500 on the expensive ones.

Per-email pricing (Brevo) charges for sends, not storage. List size barely matters; frequency is everything. On this axis, $50 buys either a huge list emailed rarely or a small list emailed constantly — and the same business can be under or over the line depending on its sending calendar.

Tiered pricing (Flodesk) charges by subscriber band with a flat rate inside each band. Flodesk retired its famous unlimited flat rate for new signups on December 2, 2025, so it now behaves like a per-contact tool with wider bands: Pro is $28 a month at 1,000 subscribers and $59 at 5,000, crossing $50 somewhere between those two sizes.

One more mechanism decides the race before any of these: contact definition. Mailchimp bills stored contacts, including unsubscribed ones until you archive them by hand, so a neglected list raises its own bill. MailerLite bills active subscribers only. The same nominal list can therefore sit on different tiers on different platforms — and a business migrating off Mailchimp often finds its billable count drops on arrival. We mapped the full cost curves, including what each tool costs at larger sizes, in our guide to how much email marketing software costs.

The under-$50 table (monthly billing, researched 2026-10-29)

Bold takeaways from the table:

• At 5,000 contacts, exactly two per-contact tools stay under $50: MailerLite and Moosend. Everything else in the mainstream field is $54 to $75. That is the whole under-$50 market at that size, and it is why those two names dominate every budget discussion.
• At 1,000 contacts, the field is wide open. Six tools sit between $9 and $28. The decision at this size is about features and automation depth, not price — the spread is under $20 a month.
• At 10,000 contacts, the $50 budget is effectively dead for paid plans with automation. The cheapest per-contact options are $79 to $110. The only under-$50 routes at that size are a free tier or Brevo’s send-based billing at low frequency.
• GetResponse Starter’s $19 headline deserves a footnote: it allows exactly one automation workflow. A welcome series plus anything else — a nurture sequence, an abandoned-cart flow — needs the Marketer plan at $59 a month for 1,000 contacts. If you need more than one workflow, GetResponse is not an under-$50 tool at all.

Brevo: the exception where frequency, not list size, sets the bill

Brevo is the only major tool in this roundup that bills per email sent, and it breaks every rule in the table above. Standard starts at $18 a month for 5,000 emails, $35 for 10,000, $69 for 20,000, and $89 for 40,000. Starter is cheaper ($9 for 5,000 emails) but has no automation, so Standard is the honest comparison for a business that needs welcome sequences.

Work it through for a 5,000-contact list:

• Emailed once a month (5,000 sends): Standard costs $18. The cheapest option in this entire article.
• Emailed twice a month (10,000 sends): Standard costs $35. Still comfortably under $50.
• Emailed weekly (20,000 sends): Standard costs $69. Over budget — and now more expensive than MailerLite Comfort at the same list size.

So a business with a large, quiet list — past customers emailed for seasonal promotions, a membership base contacted a few times a year — should price Brevo first. A business that emails weekly should not: the per-contact tools are cheaper at that frequency, and the gap widens with every extra campaign. Two more Brevo details matter at this budget: Starter keeps Brevo branding unless you pay extra for removal, which erodes its headline advantage, and the cheap send bands cap stored contacts (500 at 5,000 emails, rising to 500,000 only from the 20,000-email band), so a large list can push you into a higher band than your send volume alone requires. Our MailerLite vs Brevo comparison works through that crossover in detail.

The under-$50 options, product by product

MailerLite Comfort — the best under-$50 pick for most businesses

MailerLite Comfort costs $12 a month at 500 subscribers, $19 at 1,000, $33 at 2,500, and $49 at 5,000, with annual billing saving 10 percent. It includes 50 automations, landing pages, signup forms, and the cleanest editor in the budget tier, and it bills active subscribers only — unsubscribed and bounced contacts do not inflate the bill. The constraint to know: Comfort caps monthly sends at ten times your subscriber count, so a 500-subscriber plan allows 5,000 sends. A list emailed more than twice a week can hit that wall, and the fix is the Power plan ($25 at 500 subscribers, $69 at 5,000 — over budget at that size). Our MailerLite vs Mailchimp comparison covers the head-to-head, and our how much MailerLite costs explainer maps the full ladder.

Best for: newsletters, welcome sequences, and small stores that want the best editor under $50 and will live in the tool weekly.

Moosend Pro — the cheapest full-featured paid plan

Moosend Pro costs $9 a month at 500 contacts, $16 at 1,000, $24 at 2,000, and $48 at 5,000, with annual billing saving about 20 percent (about $7, $13, $19, and $38 respectively). Every tier unlocks the same full feature set — unlimited sends, automation, landing pages, forms, A/B testing — so upgrading only changes your contact limit, never your features. There is no free plan, only a 30-day trial, and transactional email (receipts, password resets) needs the custom Moosend+ tier. Under 5,000 contacts, Moosend is the best price-for-features ratio in this roundup; past 10,000, the per-contact ladder catches up with everyone ($88 at 10,000, over budget).

Best for: businesses under about 5,000 contacts that want every feature unlocked at the lowest paid price and do not need a free tier.

Brevo Standard — the under-$50 pick for large, quiet lists

Brevo Standard starts at $18 a month for 5,000 emails and adds full automation, A/B testing, landing pages, and branding removal over Starter. As the worked example above shows, it is the cheapest option in this article for a list emailed once or twice a month, at any list size up to the send band’s contact cap. It is also the only tool here that consolidates marketing email, transactional email, and SMS in one account. The cliff to know: there is no intermediate tier between Standard’s send bands and Professional at $499 a month from 150,000 emails, so a business whose volume grows into that gap faces a jump, not a step.

Best for: large lists emailed infrequently, seasonal senders, and anyone consolidating marketing and transactional email in one account.

GetResponse Starter — under $50 only if one workflow is enough

GetResponse Starter costs $19 a month at 1,000 contacts, $29 at 2,500, and $54 at 5,000 — over budget at that size — with unlimited sends and 3 seats included. The catch is the automation gate: exactly one custom workflow. A welcome series or a nurture sequence, not both. The Marketer plan that removes the gate starts at $59 a month for 1,000 contacts. GetResponse’s free tier covers 500 contacts but carries branding and restricted automation. If your automation needs are genuinely one workflow, Starter is a solid under-$50 tool to 2,500 contacts; if they are not, cross it off and do not let the $19 headline mislead you.

Best for: simple newsletters with a single welcome sequence, up to about 2,500 contacts.

AWeber Lite — the steady mid-priced option

AWeber Lite costs $15 a month at 500 subscribers, $25 at 1,000, and about $60 at 5,000, with 3 automations, 3 landing pages, and 3 users included, and unlimited sends. Its free tier is genuinely usable — 500 subscribers, 3,000 emails a month, one automation — which makes it a good starting point that graduates into a paid plan without a migration. The distinctive extra is native paid-subscription tooling for selling to your list, which none of the other budget tools build in. At 5,000 subscribers it is over budget, but at 1,000 it is the second-cheapest option with real automation after Moosend.

Best for: creators and small businesses selling subscriptions or memberships to a list under about 2,500 subscribers.

Mailchimp Essentials — the budget-breaker

Mailchimp Essentials costs $13 a month at 500 contacts, about $45 at 2,500, $75 at 5,000, and $110 at 10,000, and it is the tool most businesses arrive comparing against. It breaks the $50 budget between 2,500 and 5,000 contacts, and two mechanisms make the real bill worse than the table: it bills stored contacts including unsubscribed ones, and it caps automations at four steps with no branching — a proper welcome sequence needs Standard ($20 at 500 contacts, $100 at 5,000). Its editor, templates, and integration ecosystem are genuinely strong, but on price alone it is the wrong pick above 500 contacts. Our how much Mailchimp costs explainer maps the full ladder.

Best for: businesses that prioritise the largest integration ecosystem over cost, at lists under about 2,500 contacts. Not recommended on price alone.

Flodesk Pro — design-first, and now priced by list size

Flodesk Pro costs $28 a month at 1,000 subscribers, $59 at 5,000, and $79 at 10,000 (Lite is $25 at 1,000 subscribers, capped at 25,000). The design-first editor still produces some of the most visually impressive emails at this price, and automation covers basic sequences. But the December 2025 repricing matters for anyone reading older recommendations: the old flat $38-a-month unlimited plan is gone for new signups, and Flodesk now crosses the $50 line between 1,000 and 5,000 subscribers like any other per-contact tool. Legacy accounts keep the old rate; new accounts do not get it.

Best for: creators and brands where email design is a genuine differentiator, at lists under about 2,500 subscribers.

The free runway: staying at $0 before you need $50 at all

A $50 budget question is often really a “when do I start paying” question, and three free tiers stretch the runway considerably. Sender offers the most generous free plan in the category: 2,500 subscribers and 15,000 emails a month at $0, with automation included, and paid plans from about $9 a month. Kit (formerly ConvertKit) covers broadcasts to 10,000 subscribers free — the largest free audience anywhere — but with no automation; paid Creator starts at $39 a month for 1,000 subscribers and includes it. MailerLite’s free plan covers 250 subscribers and 2,500 emails a month, and Mailchimp’s covers 250 contacts and 500 emails. The honest rule: stay free until a cap blocks revenue — a welcome sequence you cannot run, branding you cannot remove, a campaign you cannot send — and then buy the cheapest paid tier that removes exactly that cap. Our roundup of the best free email marketing software for small business compares the free tiers in full, and our Kit vs MailerLite comparison covers the creator crossover.

What actually pushes a plan over $50

Five costs that do not appear in the headline price, in order of surprise:

1. Automatic tier upgrades. Exceed your contact or send limit by one and most platforms bump you to the next tier and bill it, without asking. A list growing past 5,000 contacts moves MailerLite Comfort from $49 to $89 in one step.
2. Automation gates. Brevo Starter has no automation; GetResponse Starter allows one workflow; Mailchimp Essentials caps journeys at four steps. The plan with the automation you need is often the next tier up, and that tier is often over $50.
3. Branding removal. Brevo Starter keeps its logo unless you pay extra. A plan chosen for its $9 headline can cost $18-plus once your emails look like your own.
4. Seat costs. Extra users run about $12 a month each on Brevo Standard. A two-person business can add $24 to a headline price that assumed one seat.
5. Send caps. MailerLite Comfort’s ten-times-subscribers cap and Brevo’s daily 300-email free limit are the two most common walls. Price the tool at the sends you actually plan, not the sends the free tier allows.

If budget is the binding constraint overall rather than just the email line, our roundup of the cheapest email marketing software for small business ranks the lowest entry costs regardless of the $50 ceiling, and our guide on how to choose email marketing software walks through the requirements checklist before you shortlist vendors.

Verdict: the under-$50 pick for your situation

Newsletter or small store, up to 5,000 contacts: MailerLite Comfort. $49 at 5,000 subscribers, the best editor in the tier, automation included, billed on active subscribers only. Switch to Moosend Pro ($48) if you want the lowest price and unlimited sends at the same size.

Cheapest paid plan, everything unlocked: Moosend Pro. $9 a month at 500 contacts, $48 at 5,000, full features at every tier. The only cost is the missing free plan — the 30-day trial is the whole runway.

Large list, rare sending: Brevo Standard. $18 a month for 5,000 emails covers a 5,000-contact list emailed monthly with room to spare. Do the send math first: weekly sending to that list costs $69 and breaks the budget.

Simple newsletter, one workflow, up to 2,500 contacts: GetResponse Starter or AWeber Lite. $19 and $25 respectively at 1,000 contacts. Pick GetResponse for the seats and landing pages, AWeber for the subscription tooling and the more usable free tier.

Design-first creator, under 2,500 subscribers: Flodesk Pro. $28 a month at 1,000 subscribers buys the best-looking emails in this roundup. Ignore any older article quoting a flat $38 unlimited plan — that price ended for new signups in December 2025.

Already on Mailchimp and the bill is the complaint: model the switch. At 5,000 contacts, MailerLite Comfort or Moosend Pro cuts a $75 Essentials bill to $48–$49, and moving to active-subscriber billing may shrink your billable count further. Migration is a weekend of rebuilding templates and flows — finite, and cheaper than a year of overpaying.

One closing principle: budget for the list you expect in twelve months, with automation switched on, at the sends you actually plan. A $50 budget is generous at 1,000 contacts, exact at 5,000, and gone at 10,000 — and the tool that fits today is the one whose year-two bill you already know. Pick that one, authenticate your domain, clean your list quarterly, and the platform line in your budget stays boring — which is what under $50 is supposed to feel like.
