IGSendMail is the affordable Constant Contact alternative for businesses that want unlimited contacts, 99% inbox deliverability, and AI-powered tools — from $19/mo, up to 83% cheaper than Constant Contact, with free 24-hour migration.
Modern automation at half the price
Constant Contact charges more as your list grows — and often bills you for unsubscribed and duplicate contacts. IGSendMail never charges per contact.
At 10,000 subscribers Constant Contact runs about $110/mo. The same on IGSendMail is $19/mo — roughly $1,092 saved a year.
Automatic SPF, DKIM, and DMARC, dedicated sending infrastructure, and built-in list verification keep your campaigns out of spam — tools Constant Contact charges extra for or leaves out.
Switch from Constant Contact in under 24 hours. Import your lists, templates, and automations with zero downtime — we'll handle it for you.
Everything you'd pay extra for with Constant Contact is included by default.
