Most founders default to whichever email platform they've heard of most — which is exactly why so many startups end up overpaying for a tool that's actively gotten worse for small senders in recent years. Five platforms, genuinely compared, with pricing checked directly against each vendor's own site.
Email marketing pricing is deceptively simple on the surface — a monthly number next to a contact count — and deceptively complicated underneath, because every platform counts things differently. Some bill by contacts stored, some by emails sent, some by both. That difference alone can mean a 2-3x swing in what you actually pay for equivalent usage, which is exactly the kind of detail a quick glance at a pricing page misses.
There's also a second, less-discussed factor worth naming upfront: deliverability. Two platforms can offer identical-looking pricing and features while landing in the inbox at very different rates, depending on their shared-IP reputation, authentication defaults, and how aggressively they police spam-prone senders on their own infrastructure. A cheaper tool that gets flagged as spam is worse than a slightly pricier one that reliably reaches the inbox — this isn't something a pricing page tells you, but it's often the difference that actually matters once you're sending real campaigns.
| Tool | Pricing Model | Entry Price | Free Tier |
|---|---|---|---|
| Brevo | Send-based, not contact-based | $9/mo (5,000 emails) | 300 emails/day, 100K contacts stored |
| MailerLite | Contact-based | Paid tiers vary | Free tier significantly reduced in 2026 |
| Mailchimp | Contact-based, scales steeply | Essentials from ~$13/mo (500 contacts) | 250 contacts, 500 sends/mo |
| ActiveCampaign | Contact-based | From $15/mo (1,000 contacts) | 14-day trial, no free tier |
| Moosend | Contact-based | From ~$7-9/mo | 30-day trial |
Brevo's real advantage is the pricing model itself — you pay for emails sent, not contacts stored. That means a growing list doesn't automatically push your bill up the way it does almost everywhere else on this page. The free tier alone is genuinely usable for an early-stage startup: 300 emails a day, forever, with no time limit and storage for up to 100,000 contacts. It also comes with basic CRM and SMS features built in rather than sold as a separate add-on.
For higher-volume senders specifically, this advantage compounds: Brevo's pricing stays flat regardless of whether you have 5,000 or 100,000 contacts stored, as long as your actual send volume fits the tier — a structural advantage over contact-based competitors that charge more purely because your list grew, even if your actual sending didn't.
MailerLite is still genuinely one of the more approachable tools for a first-time sender — a clean interface and a low learning curve that consistently gets praised in independent reviews. Worth knowing before you commit, though: its free tier was cut substantially in 2026, down to a much smaller subscriber limit than it previously offered. This changes the calculation for anyone who researched MailerLite a year or two ago and is expecting the old, more generous free plan.
Mailchimp is what most people think of first, purely from name recognition — but multiple independent 2026 comparisons agree it's no longer the best value on most measures. The free plan now caps out at just 250 contacts and 500 monthly sends, automation features are paywalled behind paid tiers, and pricing climbs quickly once your list grows past the entry brackets. The one genuine reason to still pick it: if you're already deeply embedded in its 800+ integration ecosystem, the switching cost may outweigh what you'd save elsewhere.
ActiveCampaign's actual strength is behavioral automation — multi-branch, conditional customer journeys based on deep engagement scoring, well beyond what a welcome-sequence-and-newsletter tool like Brevo or MailerLite is built for. For a startup that's outgrown simple automation and needs genuinely sophisticated lifecycle marketing, this is where you'd graduate to.
Moosend consistently shows up as one of the cheapest genuinely capable platforms in this category, with unlimited email sends included even at its entry pricing — a meaningful difference from send-capped competitors at a similar price point. For a startup that wants advanced automation features without ActiveCampaign's price tag, this is a reasonable middle path.
A great email platform can't fix a broken sending reputation. These are the fundamentals that actually determine whether your emails reach the inbox, regardless of which tool from above you choose.
Brevo covers most startups well past the earliest stage — its free tier and send-based pricing are genuinely hard to beat for typical newsletter-and-nurture-sequence usage. The real trigger to consider ActiveCampaign instead: once you need genuinely sophisticated, multi-branch behavioral automation, not just welcome sequences and regular newsletters. That's a later-stage need for most companies, not a day-one one — and paying for it before you need it is money better spent elsewhere.
Everything above is scoped for a startup's first email platform. If you're ecommerce specifically, Klaviyo is worth a dedicated look — deep behavioral segmentation tied directly to store purchase and browsing data, built for a different scale of operation than a newsletter tool. For B2B teams that need email folded into a broader CRM and sales motion, HubSpot's higher Marketing Hub tiers extend well beyond its accessible entry pricing into genuinely enterprise territory. Neither is a startup's first pick, but both are worth knowing exist once you're past that stage.
