Twilio SendGrid vs Unosend (2026): which should you pick?

Pick Twilio SendGrid if

• Fits if you already use Twilio for texts or calls and want email from the same company
• Works for apps sending about 50,000 emails a month that want address checks, with 2,500 validations on Pro

Look elsewhere if

• Tight if you stay on Essentials, with 1 teammate and 3 days of email activity
• Skip it if you want a free plan that lasts, since the trial ends after 60 days
• Pricey if you need SSO, subusers or a dedicated IP, which start with Pro at $89.95 a month
• Watch out: sending past your plan's volume can add overage charges the pricing page doesn't list
• Not for you if you want newsletters on the same plan, as Marketing Campaigns is separate, from $15 a month

Pick Unosend if

• Fits if you send a few thousand emails a month and want no subscription
• Works for developers who only need an API and SMTP relay

Look elsewhere if

• Skip it if you want a recurring free plan, because the 3,000 credits come once at signup
• Watch out: the cards say credits last 90 days with no minimum, while the FAQ data says 6 months and a $20 minimum
• Watch out: the site banner says Unosend is being acquired, with service continuing as normal
• Pricey if you need a dedicated IP, at $30 a month billed annually ($360 a year)
• Too light for marketing email, with no campaign tools on the page

Twilio SendGrid

• There is no lasting free plan: the free trial ends after 60 days and allows 100 emails a day.
• Essentials has a single teammate and keeps 3 days of email activity; dedicated IPs, subusers and SSO need Pro at $89.95 a month.
• Sending past the plan's volume can add overage charges, which the pricing page does not list.
• Email campaigns are a separate product, Marketing Campaigns, from $15 a month for 5,000 contacts and 15,000 emails.

Unosend

• The site banner says Unosend is being acquired, with service continuing as normal.
• The pricing cards and the page's structured data disagree: the cards say credits last 90 days with no minimum, while the FAQ data says 6 months with a 5-credit ($20) minimum.
• A dedicated IP is $30 per month, billed annually ($360 a year).
• There is no recurring free plan; the free credits are given once at signup.
