Which email marketing platform should I move to when my current one gets too expensive as my list grows?

If your main problem is the bill rising with your contact count, look at Brevo first. Its pricing is based mainly on how many emails you send, rather than charging more simply because you store more contacts—so it can suit a large list you email occasionally. Its free plan allows up to 100,000 stored contacts but limits sending to 300 emails per day; paid plans start at $9/month. (help.brevo.com)

A couple of alternatives, depending on how you use email:

• MailerLite — worth comparing if you want a straightforward newsletter tool with landing pages and automations. Its plans scale by subscriber count, so it may not solve the same cost problem as Brevo. (mailerlite.com)
• Kit — consider it if you’re a creator who values newsletter, audience, and digital-product features. Its free plan supports up to 10,000 subscribers, but it isn’t a like-for-like answer once you need paid-plan features. (help.kit.com)

Quick rule: if you send to a big list only a few times a month or year, compare send-volume pricing; if you send frequently or depend on sophisticated automations, compare the paid plans at your actual list size and send volume.

Before switching, check the total cost at your next list-size milestone, whether unsubscribed contacts count toward billing, and whether your forms, automations, integrations, and consent records will carry over. If you tell me your platform, list size, how often you send, and the features you rely on, I can narrow this down.

The best move depends on how often you email your list. If you send to a large list only occasionally, Brevo is usually the strongest choice. If you email frequently, a per-subscriber platform like MailerLite may still be cheaper.

Brevo is the usual pick for big lists. It bills by email volume, so holding contacts costs little. Brevo is cheap to hold a list and charges you to mail it. Its free tier covers up to 100,000 contacts with a send quota of 300 emails/day. The tradeoff is that it doesn't support A/B testing, and it limits automations to 2,000 contacts on the free plan.

MailerLite works better if you send often. Per the Omnisend comparison, MailerLite could work out cheaper if you have a high send volume relative to your list size and you're on the Power plan with unlimited emails. Its free plan has shrunk, now covering 250 subscribers and 2,500 monthly emails with three automations.

Kit suits newsletters and creator businesses. Its free plan is generous, available for up to 10,000 subscribers with unlimited broadcasts, but it lacks automation on free. Watch pricing: the September 2025 price increase pushed some existing users' bills up 70–200% for the same subscriber count, so check current rates before you commit.

Other options:

• Sender is cheap at scale. Its free plan covers 2,500 subscribers and 15,000 emails per month, and one comparison puts Standard at 50,000 contacts at ~$159/month.
• EmailOctopus and Moosend are low-cost options; one review says both start around $9/month and undercut MailerLite at most list sizes.
• Listmonk (self-hosted) avoids per-contact fees entirely, but it requires technical skill.

Before you switch:

• Check your bill for dead weight. One review warns that Mailchimp charges for unsubscribed and inactive contacts unless you manually archive them, which can inflate your bill 10–20% over what you'd expect. Cleaning your list may cut costs without switching.
• Price it at your real numbers. Calculate both your subscriber count and monthly send volume, then compare them. Since pricing varies a lot, I'd recommend getting exact quotes from the vendors before you decide.

If you tell me your list size, how often you send, and whether you need automation, SMS, or ecommerce integrations, I can narrow this to one or two platforms.

When your email marketing costs begin to spike as your list grows, it is usually because you are on a contact-based pricing model. This model penalizes you for every subscriber, including inactive ones, and often leads to steep price jumps at specific thresholds (e.g., 5,000 or 10,000 subscribers).

To save money as you scale, the most effective strategy is to look for platforms that charge based on email sending volume rather than total subscriber count.

How to Evaluate Your Next Platform

When moving to a new provider, don't look at the "entry-level" price (the cost for 500 contacts). Instead, use these criteria to protect your budget for the next 12–24 months:

1. Check the Pricing Model: Prioritize volume-based pricing (paying for emails sent) if you have a large list that you email infrequently. If you have a highly engaged, active list, contact-based pricing may still be fine, but compare the costs at 10,000 and 25,000 subscribers before signing up.
2. Account for "Dead Weight": In many platforms, you pay for every contact in your database, including those who have unsubscribed or bounced. Choose a platform that does not charge for inactive or invalid contacts if you want to keep costs predictable.
3. Evaluate Feature Gating: Some "cheap" platforms lock advanced automation, A/B testing, or reporting behind expensive, higher-tier plans. Ensure the plan you choose for your current list size includes the automations you will need as you scale.
4. Consider Your Frequency: If you send daily, your costs will rise regardless of the platform. If you send weekly or monthly, volume-based pricing (like Brevo) will almost always save you money compared to a subscriber-based plan.

A Note on Migration

Before moving, perform a "list cleaning." Remove inactive subscribers and hard bounces from your current provider. This will not only lower your bill on your new platform—regardless of their pricing model—but it will also improve your sender reputation and deliverability, ensuring your emails actually land in the inbox.

If your main problem is that your bill rises with subscriber count, I’d look first at Brevo. It prices around email volume rather than simply charging more for a larger contact list, which can work out well if you have lots of subscribers but don’t email them constantly. Its entry paid plan is listed at $9/month for 5,000 emails, and its free plan allows up to 300 emails a day. ⁹

A few alternatives, depending on what you do:

• MailerLite — a good fit for a small business or creator who wants straightforward campaigns and automations. It’s easy to use, but it still prices by active subscribers, so it may not solve the same scaling problem. ³⁴
• beehiiv — consider it if your email list is primarily a publication or newsletter and you want built-in newsletter monetization. Its free plan supports up to 2,500 subscribers; paid pricing starts at $49/month with annual billing at the listed entry tier. ¹²
• EmailOctopus — worth comparing if keeping costs low is the priority; a current comparison lists its Pro plan at $40/month for 10,000 subscribers. ¹⁰

Bottom line: Try Brevo if you send relatively few emails to a large list; compare MailerLite if you need a more traditional marketing toolkit; consider beehiiv if your newsletter itself is the product. Before switching, compare the price at your expected list size and monthly send volume, and check that your automations, forms, integrations, and unsubscribe/suppression lists will transfer.
