The SendGrid alternative that's 10x better
SendGrid is an OG SMTP server that offers drag-and-drop builders, with straightforward APIs to use. But what good is any of that if your emails end up in spam or nowhere?
Deliverability is everything. If SendGrid isn't delivering, none of its features matter.
That's why more marketers, founders, and SDRs are switching to Maxify Inbox. It's a deliverability-first alternative built to fix what SendGrid doesn't even monitor, offering:
Maxify doesn't just send emails. It gets them seen.

SendGrid doesn’t offer you unlimited email warmup, but we do!
SendGrid offers basic IP warm-up, but it's limited, manual, and only available if you pay extra for a dedicated IP. Maxify gives you unlimited email warmup across all your inboxes, powered by AI that mimics real human behavior by:
- Adapting to your content using AI
- Sending emails slowly and scaling them automatically
- Interacting with those emails (reads, replies, archives)
- Keeping your warmup running indefinitely for ongoing reputation management
The hidden cost that SendGrid won't tell you about bad email addresses
SendGrid offers basic IP warm-up, but it's limited, manual, and only available if you pay extra for a dedicated IP. Maxify gives you unlimited email warmup across all your inboxes, powered by AI that mimics real human behavior by:
- Keep deliverability high and data quality tight
- Protect your sender domain from bounce penalties
- Scan your entire list to detect invalid or risky emails
- Replace up to 100 bad addresses monthly with no manual cleanup
Why SendGrid's shared IP system is killing your deliverability
You're sharing your IP with hundreds of other senders you've never met. That's SendGrid's default (unless you pay extra). Maxify includes a dedicated IP from day one, which benefits you:
- Reputation is built solely by your activity
- Your domain isn't riding on a shared network's behavior
- You're not penalized for someone else's spammy campaigns
- ESPs (like Gmail, Outlook) recognize you as a trustworthy sender
What SendGrid does when your emails stop landing (hint: nothing)
When your emails stop landing, SendGrid gives you a knowledge base article. Maxify offers you real deliverability experts who analyze your setup, flag issues, and guide you step-by-step:
- Growth marketers sick of guessing why emails bounce
- Founders and SDRs sending cold outreach that must land
- Startups launching new inboxes that need to warm up fast
- Dev teams who want a powerful API plus deliverability muscle
- Agencies managing multiple domains that can't risk blacklisting
