Email-focused, agent-native, billed on sends rather than contacts, and BYO transport.
GetResponse is an all-in-one marketing platform. Email sits beside landing pages, a website builder, webinars, a course creator, sales funnels, and ecommerce integrations, on four plans that price by the number of contacts you hold and then let you send as much as you like. If you use more than the email half of that, the bundle is the argument, and it's a good one.
Nitrosend is an AI-native email platform, and it runs the meter the other way round. Contacts are unlimited on every plan, including Free, and the bill follows what you send, so a list that grows without being mailed never moves it. Every capability is an email API endpoint and an MCP tool before it's a screen, so the whole stack runs from one agent command, and BYO sending keys on Pro and above keep the transport where you want it while the platform above it changes. Teams weighing a bundle against a specialist usually read the GMass comparison, the GrowMeOrganic one, and the iContact one beside this, and the full comparison index lists the rest.
The two ladders measure different things. GetResponse charges on the size of your list and lets you send as much as you like on any paid plan; we charge on what you send and never count contacts. So the paid rows name both dimensions, and each column answers on its own meter. Monthly billing, in USD, before GetResponse's 18% annual discount.
| Scenario | GetResponse | |
|---|---|---|
| Free | 8,000 emails to start, then 500/mo forever. Unlimited contacts, 1 seat, full MCP, API, and CLI | 500 contacts and 2,500 newsletters/mo, 1 landing page, and the GetResponse badge on every message |
| 1,000 contacts, 20,000 emails/mo | $20 Pro: 20,000 emails, 3 seats, BYO sending and AI keys | $19 Starter: unlimited sends, but 1 custom automation workflow and AI capped at 3 uses. $59 Marketer is the rung where workflows go unlimited |
| 10,000 contacts, 100,000 emails/mo | $100 Ultra: 125,000 emails, 5 brands, 10 seats | $79 Starter or $114 Marketer at that list size, sends unlimited on both |
| 100,000 contacts, 500,000 emails/mo | $300 Enterprise: 500K to 4M+ emails at a published price, with SSO and SAML | $539 Starter, $599 Marketer, or $690 Creator. Enterprise above 100,000 contacts is quote-only |

GetResponse keeps sending while you move. Webinars, courses, and the website builder are GetResponse products, so they stay where they are.
nitro_import_contacts. Contacts, campaigns, and segments are reachable through GetResponse's REST API as well as by CSV, so the export can be scripted, and custom fields land on custom fields.nitro_send_message. Watch it for a week before a campaign follows it. Transactional sending is on every plan here, where it's a quote-only add-on on the other side.nitro_compose_flow. The triggers have equivalents on both sides: contact added, attribute changed, and event fired. Then decide what carries your reputation, because BYO sending keys on Pro and above route mail through Amazon SES, Resend, Postmark, Mailgun, or SendGrid, and GetResponse's own pool isn't one of them. What travels is the domain and its authentication history, and BYO means that only has to happen once.Picking a tool is about fit, and this is a wide product. Here's what GetResponse is genuinely good at.
You run webinars or sell courses and want them sitting against the same list you mail. Or your list is small and your send volume is enormous, where unlimited sends on a 1,000-contact plan is the cheapest thing on this page. The same goes for a team that wants one vendor for the whole funnel, landing pages and website included, more than it wants the operating surface underneath. None of those are close calls.
Email is the channel your program runs on and you'd rather run one product than seven. It's the right call too when your list is much larger than your send volume, because you stop paying for addresses you never mail. Same when you want the platform to answer to an agent end to end, including the billing, testing, and approval steps that usually send someone back to a dashboard, or when you want transactional mail in the same product with no add-on and no quote.
For the email half, yes. Campaigns, flows, segments, templates, contacts, and transactional sending are all here, and transactional isn't a separate product with a separate bill. Nitrosend specializes in email, so webinars, courses, and the website builder are GetResponse products and stay there.
It depends which meter you're on. At 1,000 contacts and 20,000 emails a month, GetResponse's $19 Starter with unlimited sends goes against our $20 Pro. At 10,000 contacts and 100,000 emails a month, it's $79 Starter or $114 Marketer against $100 Ultra. At 100,000 contacts and 500,000 emails a month, it's $539 Starter, $599 Marketer, or $690 Creator against $300 Enterprise, and their Enterprise above 100,000 contacts is quote-only.
Not an official one. There's a community-built server and a documented REST API, so an agent isn't locked out of the basics. The difference from a first-party tool surface shows at the edges: deliverability, billing, tests, and approvals are the four an agent reaches for when something goes wrong.
During the overlap, yes. Both platforms can authenticate against the same domain, so you can move one message type at a time and leave the rest sending. What you can't do is point Nitrosend at GetResponse's transport, because BYO sending keys cover Amazon SES, Resend, Postmark, Mailgun, and SendGrid. Their meter is peak subscribers for the month, so time the cutover at the start of a cycle.
