What to look for in a SendGrid European alternative
A SendGrid European alternative search often mixes three needs: EU processor posture, transactional-email reliability, and whether you want a narrow product-email API or a broad marketing suite.
Transactional vs marketing scope
SendGrid covers both product-triggered mail and marketing campaigns. Postscale is intentionally narrower: transactional sending, SMTP relay, inbound webhooks, suppressions, and privacy aliases.
EU/EEA service-data hosting
Check where message content, logs, analytics, dashboard data, backups, and support records are processed, not only where a message is handed to the mail network.
DPA and transfer safeguards
European buyers often ask for the DPA, subprocessor list, transfer-safeguard posture, and whether the provider is operated by an EU or US entity.
Suppression and webhook continuity
Before cutover, export suppressions, map SendGrid event webhooks, verify DKIM/SPF/DMARC, and ramp traffic by domain or message stream.
Why teams switch from SendGrid
EU/EEA-hosted primary service data
Postscale is operated by DNScale OÜ (Estonia, EU). Primary production service data is hosted in the EU/EEA, with documented transfer safeguards for limited infrastructure metadata where required. SendGrid is a Twilio US subsidiary.
Lower total cost
SendGrid pricing starts at a larger monthly send allowance than Postscale Starter. Compare the current SendGrid pricing page against the Postscale tier that matches your send, receive, webhook, and support workflow.
Inbound + Masked addresses included
Postscale ships transactional sending, inbound webhooks, and masked email aliases under one API key. SendGrid documents Inbound Parse and Event Webhook workflows, but not a native masked-address product.
Staged migration path
Both APIs use bearer-token authentication. A small adapter usually handles endpoint and payload differences, while SMTP-only apps can start by swapping host and credentials.
Side-by-side comparison
SendGrid is a broad email platform. Postscale is the focused alternative when the migration goal is transactional sending, inbound webhooks, suppressions, aliases, and EU/EEA-hosted primary service data.
| Feature | Postscale | SendGrid |
|---|---|---|
| Price at 10,000 sends/mo | €9 | Essentials starts at a larger published allowance |
| Price at 100,000 sends/mo | €79 | Use current SendGrid Pro pricing table |
| EU/EEA-hosted primary service data | Yes | Review current Twilio SendGrid regional docs |
| Standard DPA (no extra cost) | Yes | Review current Twilio legal docs |
| Inbound email API included | Yes | Inbound Parse Webhook documented |
| Masked email addresses | Yes (Shield) | No equivalent |
| SMTP relay | Yes | Yes |
| DKIM + DMARC auto-configured | Yes | Yes |
| XRechnung / e-invoicing | Yes (EU mandate ready) | No |
Pricing comparison: match the tier to the workflow
SendGrid pricing is plan-based and changes by allowance and feature. Use the current official pricing page, then compare the real migration workflow: API sends, SMTP relay, inbound parse, events, suppressions, and support.
| Scenario | SendGrid | Postscale | Planning note |
|---|---|---|---|
| Small transactional workload | SendGrid's paid Email API pricing starts at a larger published monthly allowance than 10,000 sends. | Starter includes 10,000 shared send + receive emails/month at EUR 9/mo. | Postscale is easier to model when the product needs both sending and receiving at low volume. |
| 100,000 product emails/month | Use the current SendGrid Pro or Essentials pricing table for this allowance. | Pro includes 100,000 shared send + receive emails/month at EUR 79/mo. | Compare the same feature set, including logs, webhooks, suppressions, and inbound workflows. |
| Inbound parse and replies | SendGrid documents Inbound Parse Webhook for posting parsed inbound email to your URL. | Postscale inbound rules send signed parsed webhooks with message and attachment metadata. | Payload shape, retry behavior, and attachment handling should be tested before MX cutover. |
| Marketing plus transactional | SendGrid includes API sending and marketing surfaces in the broader platform. | Postscale focuses on product-triggered transactional and inbound email only. | Keep marketing broadcasts on a campaign platform if you need audience management and automation. |
API migration example: SendGrid to Postscale
Keep the provider-specific payload behind a small adapter. Move one transactional template first, then widen traffic after webhook and bounce handling match.
await fetch("https://api.sendgrid.com/v3/mail/send", {
method: "POST",
headers: {
"Authorization": `Bearer ${process.env.SENDGRID_API_KEY}`,
"Content-Type": "application/json",
},
body: JSON.stringify({
personalizations: [{ to: [{ email: "user@example.com" }] }],
from: { email: "alerts@example.com", name: "Acme" },
subject: "Welcome",
content: [{ type: "text/html", value: "<p>Hello from Acme</p>" }],
}),
});await fetch("https://api.postscale.io/v1/send", {
method: "POST",
headers: {
"Authorization": `Bearer ${process.env.POSTSCALE_API_KEY}`,
"Content-Type": "application/json",
},
body: JSON.stringify({
from: "Acme <alerts@example.com>",
to: ["user@example.com"],
subject: "Welcome",
html_body: "<p>Hello from Acme</p>",
tags: ["onboarding"],
}),
});Deliverability checks before moving from SendGrid
Provider changes do not transfer sender reputation by themselves. Keep the sender domain, authentication, suppression history, and ramp plan stable while you compare results.
Authentication parity
Publish Postscale DKIM, SPF, return-path, and DMARC-compatible records beside the existing provider records before production traffic moves.
Suppression continuity
Export hard bounces, spam complaints, unsubscribes, and manual suppressions from the old provider, then import them before the first live send.
Segmented cutover
Move one stream first, such as password resets or low-volume notifications, then widen only after delivery events and complaint rates look normal.
Webhook reconciliation
Run old and new webhook handlers together during cutover so delivery, bounce, defer, and complaint state stays observable.
EU hosting and compliance proof points
Use these checks when comparing EU email API alternatives. Server location matters, but so do processor agreements, subprocessors, retention, and the entity operating the service.
SendGrid EU alternatives to evaluate
A useful shortlist includes dedicated transactional APIs, broader marketing suites, and cloud-provider email services. The right fit depends on whether you need sending only, inbound routing, privacy aliases, or simpler legal review.
Postscale
EU-operated product-email API with REST, SMTP relay, inbound webhooks, suppressions, masked addresses, DMARC reporting, and EU/EEA-hosted primary service data.
Best for
Product teams that want to move transactional sending and inbound workflows away from a broad US-first email suite.
Brevo
France-based marketing and transactional email suite with CRM, SMS, automation, SMTP, and REST API surfaces.
Best for
Teams that need a European replacement for both SendGrid Marketing Campaigns and transactional email.
Mailjet
France-based email platform combining collaborative marketing email tooling with transactional email delivery.
Best for
Teams that want campaign collaboration and transactional delivery in one European platform.
Scaleway Transactional Email
Cloud-provider transactional email service from Scaleway with SMTP/API sending for teams already using European cloud infrastructure.
Best for
Infrastructure-oriented teams that need sending primitives more than marketing tooling.
Migrate from SendGrid in under an hour
Point your domain
Add Postscale's two DKIM CNAMEs and an SPF include. DNS propagation is minutes. Our dashboard verifies each record live.
Swap the credentials
Replace SendGrid's API key or SMTP credentials with Postscale's. Field shapes are close enough that a small HTTP wrapper usually handles the endpoint change.
Cut over
Test a few messages to a seed list, confirm DKIM/DMARC pass, then move a small production segment before increasing traffic gradually. Keep the old SendGrid account active for rollback.

Frequently asked questions
What is a SendGrid European alternative?
A SendGrid European alternative is usually an email provider operated from Europe or built around EU/EEA service-data hosting. Postscale focuses on product email: REST sending, SMTP relay, inbound webhooks, suppressions, and privacy aliases.
Does SendGrid offer EU/EEA-hosted primary service data?
SendGrid is a Twilio US product. If EU/EEA data hosting is part of your requirement, review the current Twilio DPA, subprocessors, transfer safeguards, and data-location commitments before deciding.
Does the migration risk my sender reputation?
Warm up carefully. We support dedicated IPs and paced volume ramps so you can move traffic gradually, but inbox placement still depends on your sender history, list quality, and authentication.
What about event webhooks?
Postscale fires HMAC-signed webhooks on delivered, bounced, deferred, and complained events. SendGrid's engagement events do not have a Postscale equivalent yet.
Do you support Marketing Campaigns too?
No. Postscale is focused on transactional + inbound. If you run marketing broadcasts, keep those on a dedicated tool — we'll integrate at the unsubscribe and suppression level.
Can I keep my existing unsubscribe list?
Yes. Export your SendGrid suppressions (bounces, spam reports, unsubscribes) as CSV and upload to Postscale. Takes five minutes, prevents re-sending to anyone you already shouldn't.
Can I keep marketing campaigns on SendGrid?
Yes. Many teams split marketing from product-triggered mail. Keep campaigns in SendGrid or another marketing platform, then move transactional sending and inbound workflows to Postscale.
