Is SendGrid free? What it actually costs in 2026
Yes, there is a free tier — with limits.
Free for 100 emails a day. Essentials from about $20/month for 50,000; Pro from around $90 for 100,000 with a dedicated IP; higher volumes quoted. Marketing Campaigns and dedicated IPs are separate line items. The step that catches people is the jump from free to Essentials — 100 a day is very little, and the next tier is a real monthly commitment for an application sending a few thousand.

When paying is still the right call
Stay if deliverability is business-critical and you do not want to own it — a shared warmed IP pool is genuinely valuable and reproducing it takes time you may not have. Stay for the analytics and the marketing tooling if non-technical colleagues rely on them. Stay if you are inside the free tier and 100 a day is enough. And stay if your volume is high enough that the enterprise deliverability support is doing real work, because at scale a spam-folder problem costs more than the invoice.
What you are locked into
Low, and worth knowing before anyone quotes you a migration. Sending is SMTP or a simple API, so switching is credentials and an endpoint. Templates export. What genuinely does not transfer is sender reputation: a new IP or domain starts cold, and mail from a cold IP lands in spam until it is warmed over days or weeks. That is the real cost of switching email providers, it is invisible on a feature comparison, and it is why migrations are staged rather than cut over.
