Frequently Asked Questions

For an early-stage company the best platform is one you can start on for free, automate from day one, and grow into without a pricing cliff. Prioritize a real free tier, automation on every plan, an API your engineers will actually use, and pricing tied to emails sent rather than list size. IGSendMail checks each of those boxes, with a free plan and paid tiers from $19 per month.

Yes. The IGSendMail free plan includes 2,500 contacts and 3,000 emails per month, with automation and built-in email verification included. There is no credit card requirement and no time limit. When you outgrow it, Starter is $19 per month ($15 billed annually) with unlimited contacts and 50,000 emails, so the jump is predictable rather than a surprise.

On IGSendMail, cost scales with sending volume, not list size. Free covers 2,500 contacts and 3,000 emails per month. Starter is $19 per month ($15 annually) for 50,000 emails, Pro is $49 ($39 annually) for 100,000, and Business is $99 ($79 annually) for 300,000. Every paid plan includes unlimited contacts, so a SaaS product with a large free-user base is not penalized for storing them. Full details are on the pricing page.

Yes. IGSendMail provides a REST API and an SMTP relay. Use the API to add a contact the moment someone signs up, tag them by plan or activation step, and start an onboarding automation, or send transactional messages such as password resets and receipts through the relay. Zapier, Segment, and Stripe integrations are available if you would rather connect without writing code.

IGSendMail offers a free done-for-you migration completed within 24 hours. Export your contacts, tags, and templates from Mailchimp, HubSpot, or any other tool, share them, and the team sets them up in your new account. If you prefer to do it yourself, CSV import and the REST API are available. There is no charge either way, and you can keep sending from your old platform until you are ready to switch.

New domains have no sending reputation, so authentication and list quality matter most. IGSendMail configures SPF, DKIM, and DMARC automatically when you connect your domain, and built-in email verification removes invalid and disposable addresses before they cause bounces. IGSendMail reports 99 percent inbox placement. For a deeper look at warming up and monitoring a new domain, read the email deliverability guide.
