Buffer vs Mailchimp
Both are marketing tools. Here is what separates them.
What Buffer is
Buffer is a social media scheduling tool. Posts are written once, dropped into a queue for each connected channel and published on a schedule. It supports Bluesky, Facebook, Google Business Profile, Instagram, LinkedIn, Mastodon, Pinterest, Threads, TikTok, X and YouTube, and runs as a web app, a mobile app and a browser extension. The product is divided into Publish, Create, Community, Insights, Collaborate, Start Page, AI Assistant and API. Pricing is charged per connected social channel rather than per account, and that single decision determines whether Buffer is cheap or expensive for a given team. Essentials is listed at $5 per month per channel and Team at $10 per month per channel with unlimited team members included, so a five-person team posting to three channels pays less than one person posting to eight. Channels 1 to 10 are charged at the standard rate and each channel beyond the tenth costs less, which softens the curve for anyone managing a large roster. The Free plan costs $0, is described as free forever, is for a single user and connects three channels, with a cap of 10 scheduled posts per channel at a time. Paid plans lift that cap to unlimited scheduled posts per channel and add API access, the AI Assistant and unlimited saved ideas. They come with a 14 day free trial. Core analytics are free rather than held back for paying customers. Insights reports reach, engagement, follower changes and top-performing content, compares channels side by side and tracks trends over time. Every metric carries its own definition and a stated refresh frequency, which is useful when a figure disagrees with the native platform and someone has to explain why. Takeaways are AI-generated summaries of performance with suggested actions. Paid plans extend how far back the analytics history goes and add PDF and CSV exports for reporting outside the tool. Start Page is Buffer's link-in-bio page builder, available on the free plan with some feature limits alongside the three connected channels. Its appearance is set with themes, colours, fonts and layouts, and pages can embed videos, products, photos and forms without code. Built-in analytics show which links are getting the most clicks, so the page can be judged on the same terms as the posts pointing at it.
What Mailchimp is
Mailchimp is an email marketing platform for holding a contact list, sending campaigns to it and automating the follow up. Audience tooling covers segmentation, tags, customer profiles, behavioural targeting, predictive demographics and sign up forms, and the product also includes landing pages, webhooks, a Content Studio for creative assets and generative AI copy tools. Four marketing tiers are sold: Free, Essentials, Standard and Premium. What separates them is less the feature list than the sending allowance, which is set as a multiple of the contact count: 10 times on Essentials, 12 on Standard and 15 on Premium. Seats and audiences follow the same ladder, from 1 seat and 1 audience on Free, to 3 and 3 on Essentials, 5 and 5 on Standard, and unlimited on Premium. The Free plan caps the audience at 250 contacts and sending at 500 emails a month or 250 a day, and it pauses sending once either limit is passed. Paid plans behave differently. Exceeding a contact or send limit triggers an overage charge instead of a pause, so a fast growing list raises the bill rather than stopping the sending, which is worth understanding before it happens. Essentials limits automation to flows of up to 4 steps, which covers a welcome sequence and not much more. Standard supports up to 200 automation flows and adds custom coded templates, dynamic content and custom reports. Premium adds multivariate testing, predictive segmentation, phone and priority support, a dedicated onboarding specialist and migration services. SMS marketing is available on paid plans only. Optimisation features include A/B testing, send time optimisation and a subject line helper, and more than 300 integrations are listed. Audiences above 200,000 contacts need a custom quote from the sales team. For anyone who mails infrequently there is a credit based Pay As You Go option instead of a subscription, and qualified nonprofit organisations get a 15 percent discount. The pricing page can be switched between sixteen currencies, including GBP, EUR, AUD, CAD, INR and ZAR. Transactional email is priced separately, in blocks, where one block is a credit for 25,000 emails. The rate falls with volume, from 20 USD per block for 1 to 20 blocks down to 10 USD per block at 161 blocks and above. Unused credits do not carry from one month to the next, so buying ahead of demand wastes money. Verifying a sending domain earns up to 500 free sends, and a dedicated IP is a 29.95 USD monthly add on.
