beehiiv vs CPM Calculator

beehiiv

The newsletter platform built for growth

beehiiv is a newsletter platform built by people who ran one of the largest newsletters in the world, and it shows in what it prioritises: growth mechanics and monetisation are first-class features rather than add-ons bolted onto an email sending tool. The team came out of Morning Brew, which means the product was designed by operators who had already solved the problems most newsletter tools leave to the writer. Referral programs, recommendation networks where publications send each other subscribers, paid acquisition tracking, SEO-friendly hosted web archives, and a built-in ad network are all part of the platform. That last one matters more than it sounds: the single hardest part of running a newsletter as a business is selling sponsorships, and beehiiv will match publications with advertisers rather than leaving a writer to cold-email brands. Monetisation runs on two tracks - paid subscriptions with Stripe, and ad revenue - and the platform does not take a percentage of subscription revenue on paid plans, which is a meaningful difference from Substack's model. Pricing is freemium: a free tier covers a real audience, and paid tiers unlock the growth and monetisation tooling as the list grows. The comparison set is crowded and the trade-offs are clear. Substack is simpler and comes with a built-in discovery network, but it takes a cut of your revenue and owns more of the relationship with your readers. ConvertKit and Kit are stronger as marketing automation for creators selling products, with better sequences and tagging, but weaker as a media business. Ghost is open-source and self-hostable with full ownership, and is the better choice if you want a website with a newsletter attached rather than a newsletter with a website attached. Mailchimp and MailerLite are general email marketing tools that happen to send newsletters, which is a different job. Choose beehiiv when the newsletter is the business - when you intend to grow the list deliberately, sell sponsorships, and eventually run it as a media property. It is over-specified for a founder who just wants to email their users occasionally, and under-specified for a company that needs lifecycle email tied to product events. The honest caveat is portability: as with any hosted newsletter platform, you own the list but not the infrastructure, so evaluate the export path before you build a business on top of it.

CPM Calculator

Free advertising calculators for CPM, spend, impressions, CPC, CTR, and eCPM.

CPM Calculator is a free browser-based toolkit designed for advertisers, marketers, publishers, media buyers, freelancers, and small businesses that need to plan and evaluate digital advertising campaigns. The main calculator lets users enter any two values among CPM, total ad spend, and impressions, then instantly calculates the missing value. This makes it easy to estimate campaign costs, compare media plans, and check whether a proposal fits an available budget. The website also includes focused calculators for CPC, CTR, eCPM, break-even ROAS, campaign reach, campaign comparison, and YouTube earnings. Each calculator explains the formula, shows the result immediately, and keeps the workflow simple for users who do not want to build spreadsheets or search for formulas. The tools are useful for planning new campaigns, reviewing past performance, comparing advertising channels, and communicating estimates with clients or teammates. CPM Calculator works directly in the browser and does not require an account, installation, or subscription. Users can select a currency label, enter their campaign data, and receive results without hidden currency conversions or unnecessary steps. The responsive interface works on both desktop and mobile devices. Unlike a large advertising platform, CPM Calculator is independent of any particular advertising network. It focuses on transparent calculations and practical planning tools that can be used across display advertising, social media campaigns, video advertising, publisher inventory, and other paid media channels. All core calculators are free to use.
