Email marketing with unlimited contacts
IGSendMail is an email marketing platform with unlimited contacts on every paid plan, starting at $19/mo for 50,000 emails a month. You never pay more as your list grows, and you're never billed for unsubscribed or duplicate contacts — unlike Mailchimp, Klaviyo, and Constant Contact, which charge by the subscriber.
Truly unlimited contacts
Import 5,000 or 500,000 subscribers — your plan price stays the same. No tiers that quietly bump you to the next bracket.
No per-subscriber pricing
Per-contact billing punishes the exact thing you're working for: list growth. IGSendMail charges a flat rate so growth never raises your bill.
Stop paying for unsubscribes
Most platforms keep charging for unsubscribed and inactive contacts. We don't count them — you only ever pay your flat plan price.
Predictable, capped costs
Know exactly what you'll pay every month. Budget with confidence instead of bracing for the next contact-tier increase.

Unlimited contacts — FAQs
Is it really unlimited contacts?
Yes. Every paid IGSendMail plan includes unlimited contacts. Your price is based on monthly email sends, not how many subscribers you store — so growing your list never increases your plan price.
Do you charge for unsubscribed or inactive contacts?
No. Many platforms keep billing you for unsubscribed and inactive contacts. IGSendMail never counts them against you.
What do I actually pay for then?
A simple flat monthly plan ($19 / $49 / $99) tied to your monthly email send volume. Contacts are always unlimited on paid plans.
How much can I save vs per-contact pricing?
At 25,000 contacts IGSendMail is $49/mo versus roughly $230/mo on Mailchimp and $350/mo on Klaviyo — often a saving of thousands of dollars per year.
Is there a free plan?
Yes — a free plan covers up to 2,500 contacts so you can start at no cost, then move to an unlimited-contact paid plan when you're ready.
How much is Mailchimp for 500 contacts?
Mailchimp bills by contact tier, so 500 contacts lands in its lowest paid bracket and the exact figure depends on the plan you choose — check current pricing on Mailchimp's site, since tiers change. IGSendMail doesn't price by contact at all: the free plan covers up to 2,500 contacts and 3,000 emails a month, and every paid plan from $19/mo includes unlimited contacts, so 500 contacts cost the same as 50,000.
Can I send unlimited bulk emails for free?
Not unlimited — no reputable platform offers unlimited free sending, because deliverability depends on managed infrastructure. IGSendMail's free plan includes 3,000 emails a month to up to 2,500 contacts with no credit card. When you need more, Starter is $19/mo for 50,000 emails, Pro is $49/mo for 100,000, and Business is $99/mo for 300,000 — all with unlimited contacts.
