Buyer guide

Best SendGrid alternatives

SendGrid covers both API and marketing use cases at very large scale, and for high, steady volume with a dedicated IP it remains a sensible default. Teams move for reasons that cluster tightly: overage bills, marketing and transactional sharing one volume cap, and support that is thin at the tiers most companies are actually on.

Why teams leave

  • On the API plans, marketing and transactional sends draw down the same monthly cap, so a campaign can consume the allowance receipts depend on.
  • Overage bills rather than stopping, so a retry loop becomes an invoice.
  • Marketing Campaigns is billed separately from the Email API, meaning two subscriptions for one product.
  • Support at the lower tiers is slow, and it is felt hardest during a deliverability incident.

The options

1Postmark

Focused transactional streams with the best delivery diagnostics in the category.

Pricing
From about $15/mo for 10,000 messages, overage near $1.80 per thousand.
The catch
Costly above roughly 10,000 messages a month, and no marketing lists or broadcasts.

2Resend

Developer-first teams who want polished tooling and React Email.

Pricing
$20/mo for 50,000 emails; marketing from $40/mo at 5,000 contacts.
The catch
Marketing features are light, and the two products are billed separately.

3SendKernel

Small teams wanting one guarded workflow, with sending and marketing metered separately.

Pricing
$18/mo for 50,000 emails, $36/mo for 5,000 contacts, $54 for both.
The catch
No dedicated IP at any price, which rules us out above a few hundred thousand messages a month. No automation journeys or landing pages.

4Amazon SES

Lowest infrastructure cost when your team will build and own the product layer.

Pricing
About $0.10 per thousand messages.
The catch
No contact storage, unsubscribe handling, suppression, dashboard, or compliance enforcement. All of it is yours to build and maintain.

5Brevo

Volume-based pricing with automation, SMS, and a light CRM included.

Pricing
Free tier around 300 messages a day; paid from roughly $9/mo.
The catch
A broad suite, so more product to learn than an API-first team usually wants.

Moving your list

Export contacts with unsubscribe status, and export the suppression list as a separate file — SendGrid keeps them apart and the suppression file is the one teams forget. Verify your domain at the new provider while SendGrid's DKIM records stay published, move transactional traffic first, and keep campaigns where they are until delivery looks healthy.

Questions people actually ask

Why is my SendGrid bill higher than the plan price?
Almost always overage, which bills per extra email rather than stopping at the limit — on the order of $0.001 each, which is invisible until a retry loop or a doubled import runs overnight. The other common cause is paying for Marketing Campaigns and the Email API as two subscriptions without realising they are separate.
What is the best SendGrid alternative for transactional email?
Postmark if delivery diagnostics are what you want and your volume is low; Amazon SES if you have engineers and volume above roughly a million a month. Between those, most platforms sit within a narrow band on price, so the deciding factors are overage behaviour and whether marketing and transactional share a cap.
Do I need a dedicated IP after leaving SendGrid?
Below roughly 100,000 messages a month, no — and buying one usually makes delivery worse, because an IP with irregular volume never establishes a reputation and unknown IPs are treated with more suspicion than a well-run shared pool. Above a few hundred thousand a month it starts to matter, and that is a reason to stay with a provider that offers one.
