Is SendGrid a Scam or Legit? Here's What the Record Shows.
Transactional email API and marketing platform — reliable infrastructure with a support deficit
Short answer: Not technically — but it's complicated.
Our read
SendGrid isn't a "scam" in the criminal sense — it's a real company with real software — but the complaint record raises serious questions about its sales practices, billing, and the gap between what's advertised and what's delivered.
The strongest "this feels like a scam" signals tend to come from one of two places: marketing claims that don't match reality, or billing practices that make leaving harder than joining. Below are the 4 flags in those two categories we've documented for SendGrid.

Cancellation Process Traps Users in Recurring Charges
Multiple Consumer Affairs and SiteJabber reviews describe a cancellation experience where users believed they had downgraded or cancelled their account, only to receive another month's charge. The account management interface reportedly requires navigating several confirmation steps to truly cancel, and users who miss the billing cycle cutoff by even a day are charged in full for the next period. Complaints spiked in early 2024 around the same time Twilio was restructuring pricing across its product portfolio.
"I cancelled — or thought I did — in November. Got charged again in December for the full month. Support said I hadn't completed all the cancellation steps and refused to refund the $89."

Unexpected Overage Charges and Opaque Plan Upgrade Billing
Complaints on G2 and Capterra consistently flag SendGrid's billing behavior around email volume overages. Users report being charged for emails they didn't intend to send — often because of misconfigured integrations or test sends — with no proactive alert before the charge hit their card. Several small business owners noted charges of $150 to $400 appearing on statements without any in-app warning that they'd crossed a tier threshold. Refund requests are routinely denied with reference to the terms of service.
"Got hit with a $280 charge for going over my plan limit by a few thousand emails. No email warning, no dashboard alert. Just a charge. And of course, no refund because 'usage-based billing.'"

Deliverability Guarantees That Don't Reflect Shared IP Reality
SendGrid markets itself heavily on deliverability, but users on shared IP pools — which covers virtually every plan below the Pro tier — are at the mercy of other senders on the same IPs. G2 and Trustpilot reviewers have noted that their open rates dropped significantly after being placed on shared IPs with poor sender reputations, despite SendGrid's marketing implying strong deliverability as a given. Getting a dedicated IP requires upgrading to a $89.95/month plan, a cost constraint that isn't surfaced clearly during signup.
"The marketing says 'industry-leading deliverability.' What they don't say upfront is that you're sharing an IP with whoever else is on your tier. My open rates tanked and I had to pay more just to get a clean IP."

Account suspensions for spam violations affecting legitimate senders
SendGrid's spam detection systems have a documented pattern of flagging legitimate transactional email senders — particularly those with list segments that have high bounce rates or older acquired lists. Account suspension without warning is reported regularly.
