SocketLabs features: what you get on each plan
SocketLabs ships 12 of the 16 features we test, and the gating is unusual for a relay: the suppression list, the one control an ESP normally hands you on day one, is an Enterprise-only feature. Webhooks are counted rather than unlimited, one endpoint on $39.95/mo Core and five on Pro. The best-value line on the whole table is the dedicated IP, included at $89.95/mo.
Three plans carry features: Core, Pro 100k and Enterprise. There is no free tier, only a first month at $0 on Core. Every line below was read on 14 September 2026 against two sources that agree: the SocketLabs pricing page, and the SocketLabs help center. Where the help center is silent, the line says so instead of guessing.
SocketLabs is a sending relay that also carries a real marketing surface, which is rarer than it sounds in this category. Newsletters, drip campaigns, web signup forms and a template editor are all documented under Marketing Tools and all available from the entry plan. What it does not carry is split testing or address validation, and neither appears in the pricing table or the help center.

How to read this table
Three gates decide what SocketLabs costs you in practice. The first is suppression. Most relays treat a managed suppression list as table stakes; here it sits on Enterprise, which means a Core or Pro sender is holding that list somewhere else and reconciling it by hand. Budget for that work, or budget for Enterprise.
The second is the webhook count. One endpoint on Core is enough for a single application and awkward the moment you want delivery events in one system and complaints in another. Five on Pro is comfortable. Nothing in either source suggests you can buy extra endpoints without changing plan.
The third is retention, and it is the quietest of the three. Core keeps logs for 10 to 90 days depending on the report; Pro keeps 30 to 180. If your support team answers questions about mail sent last quarter, the entry plan will not have the record.
Two absences are worth naming because comparison pages routinely imply otherwise: there is no split testing and no address verification tool. Both would be listed in the pricing table or the help center if they existed, and neither is.
