EmailJS suits apps sending through existing email providers, but its request caps and dropped overages deserve a close look before you scale. These seven alternatives cover API-first sending, transactional email, SMTP relays and testing. Listed starting prices range from $5.60 for MailerSend to $19.95 for Twilio SendGrid; some vendors also list free plans, but the caps and paid pricing differ. If your real need is collecting newsletter signups, an email-sending service may not be the right category.
01Why people leave EmailJS
Request caps and dropped overages
The published EmailJS summary flags request caps and dropped overages. Check what happens when your app reaches its limit before switching.
You need a subscriber list
A Reddit thread about signup forms distinguishes email APIs from tools for capturing and managing newsletter addresses. Confirm the service solves the right problem.
Delivery concerns need investigation
One Reddit commenter reported SendGrid delivery problems and said they moved to Postmark. Treat that as an individual report, not a guarantee.
02The alternatives, ranked by fit
- Developer-first sending
ResendResendResend is a natural alternative if you want developer-focused transactional email rather than EmailJS’s provider-flexible approach. Its listing includes a free tier and API-first campaign tools, which may suit a small app that is growing beyond basic app-triggered email. The paid starting price is not published, so check the current pricing before budgeting a move.
Trade-off: Paid pricing is undisclosed, and reliability reports are mixed.
7.2/10from
Freefree plan - Transactional email
PostmarkPostmarkPostmark fits applications where transactional email is the main job. Its listed tools include separate message streams and inbound email processing, and pricing starts at $15 with a free plan. That gives you a clearer plan to compare against EmailJS’s request limits. A commenter on Reddit said they switched from SendGrid to Postmark after delivery issues, but that is one user’s report.
Trade-off: The free tier is small; agency costs warrant scrutiny.
7.4/10from
$15/mofree plan - Flexible app messaging
MailerSendMailerSendMailerSend is worth comparing if EmailJS’s request limits are getting in the way and you want more than email alone. Its listing covers transactional email, SMS and WhatsApp, with a free plan and a $5.60 starting price. Check the exact caps and add-on costs against your sending needs before you move; the low entry price does not settle total cost.
Trade-off: Caps, add-ons and support caveats need checking.
7.2/10from
$5.60/mofree plan - API and SMTP
MailgunMailgunMailgun offers both API and SMTP, plus email validation tools, making it a candidate if EmailJS’s existing-provider setup no longer suits your workflow. The listed starting price is $15 and it has a free plan. But the free tier is capped at 100 emails per day, so treat it as a narrow testing option rather than assuming it will cover ongoing app traffic.
Trade-off: The free plan’s 100-email daily limit is restrictive.
7.2/10from
$15/mofree plan - Small-volume relay
SMTP2GOSMTP2GOSMTP2GO is a straightforward option to compare when you want transactional delivery with reports and support channels. Its listing includes a free plan and a $10 starting price, which gives small senders a paid baseline to weigh against EmailJS. The fit is strongest for modest volumes; compare its fixed starting cost with usage-based options before choosing.
Trade-off: The $10 starting price may not suit low usage.
7.8/10from
$10/mofree plan - Testing and sending
MailtrapMailtrapMailtrap may fit teams that need to test staging emails as well as send them. Its listing combines testing and sending, with a free plan and a $12 starting price. That is a different emphasis from EmailJS’s app-triggered email through existing providers. Check each Mailtrap product’s separate price and usage caps before treating the starting price as your total.
Trade-off: Testing and sending have separate prices and caps to check.
7.2/10from
$12/mofree plan - API plus campaigns
Twilio SendGridTwilio SendGridTwilio SendGrid bundles email API sending with campaign tools and SMTP, so it may suit teams that want transactional and marketing email in one toolkit. Its listed starting price is $19.95. Check sending caps and account approval risk first. One Reddit commenter reported delivery problems and said they were advised to upgrade for a dedicated IP; that account is not proof every sender will have the same experience.
Trade-off: Check sending caps, approval risk and delivery reports.

Questions people ask
Which EmailJS alternative is best for a newsletter signup form?
If the main job is collecting and managing subscriber addresses, an email API may be the wrong category. In a Reddit thread, commenters suggested bulk email or newsletter services, or a form-capture tool, for that use case. The alternatives on this page focus on email sending, so check their fit before switching.
Which EmailJS alternative has the lowest listed starting price?
Among these picks, MailerSend has the lowest listed starting price at $5.60 and includes a free plan. That figure alone does not establish the cheapest option for your usage: compare each service’s caps, add-ons and paid pricing. Resend’s paid starting price is not published on the vendor's site.
Are there Reddit reports of SendGrid delivery problems?
Yes. One commenter in a Reddit thread said they had delivery issues with SendGrid and were advised to upgrade to a plan with a dedicated IP; they said they switched to Postmark. That is an individual report, not a prediction of your results. Check current plan terms and your own delivery requirements.
