NYLAS VS UNIPILE · UPDATED OCTOBER 2026
Nylas vs Unipile: the best Unipile alternative for email and calendar APIs in 2026
Unipile and Nylas both connect an app to Gmail, Outlook and IMAP mailboxes through one API. Unipile also covers LinkedIn, WhatsApp, Instagram and Telegram messaging. Nylas adds Yahoo, iCloud and Exchange on-premises, a Contacts API, Notetaker and Agent Accounts, and its paid plans start at $15 a month for 10 accounts, against Unipile’s $55.

SOC 2 Type II, ISO 27001 and ISO 27701, with a pre-signed HIPAA BAA on paid plans
Why teams look for a Unipile alternative
Teams usually look beyond Unipile for three reasons: a $55 monthly minimum, no contacts or meeting products, and mail coverage limited to Gmail, Outlook and IMAP.
A $55 monthly minimum
Unipile’s minimum is $55 a month for up to 10 linked accounts, then $5.50 per account from 11 to 50. Nylas Essentials is $15 a month for 10 accounts, then $2.25 per additional account. Unipile charges nothing per request or message. Sources: unipile.com/pricing-api, nylas.com/pricing
No contacts or meeting products
Unipile’s API covers messaging, email, calendar and social profiles, and its only contacts endpoint is for LinkedIn relations. Nylas adds a Contacts API, Notetaker for meeting recording and Agent Accounts. Source: unipile.com/pricing-api
Mail coverage limited to Gmail, Outlook and IMAP
Unipile’s FAQ lists Gmail, Outlook and IMAP for email. Yahoo and Apple accounts connect through IMAP with a password, and Exchange on-premises isn’t listed. Nylas connects Yahoo through OAuth, plus iCloud and Exchange on-premises. Sources: unipile.com/pricing-api, Unipile link email accounts docs

Unipile email API alternative
One auth flow for every mail provider
Nylas connects Gmail, Microsoft 365, Yahoo, iCloud, IMAP and Exchange on-premises behind the same auth flow and schema. Each connected account is one grant, so your code reads mail the same way whichever provider a user brings.
- Yahoo through OAuth Users sign in with Yahoo instead of typing an app password into your product.
- iCloud mail and calendar Connect Apple users’ email and calendar through the same integration.
- Exchange on-premises Reach self-hosted Exchange servers through EWS, alongside Microsoft 365.
- One schema across providers Messages, events and contacts share the same fields on every provider.
Real-time webhooks
Webhooks for every message, event and contact change
One webhook subscription covers email, calendar, contacts and Notetaker, so your app reacts to changes across every connected account without polling.
Signed notifications
Every webhook is signed with HMAC-SHA256 so you can confirm it came from Nylas.
Data in the payload
Notifications include the changed object, so most changes need no follow-up API call.
One subscription for every grant
A single webhook endpoint receives changes from every connected account.
Configurable triggers
Subscribe only to the message, event, contact and grant changes your app needs.

}What Nylas covers that Unipile doesn’t
Three capabilities have no listed equivalent on the Unipile side.
Contacts API
Read and write contact records across Google and Microsoft accounts, with webhooks when they change. Unipile lists contacts only for LinkedIn relations.
Notetaker
A bot that joins Google Meet, Microsoft Teams and Zoom to record, transcribe and summarize meetings, on every Nylas plan. Meeting data sits beside the same user’s email and calendar.
Agent Accounts
Give an AI agent its own inbox and calendar, created in one API call, so it can send, receive and schedule as itself.
Pricing comparison
Both charge by connected account. Nylas plans include a set number of accounts plus contacts, Notetaker and Agent Accounts; Unipile charges one rate per linked account, tiered by volume, with no other usage fees.
| Dimension | Nylas | Unipile |
|---|---|---|
| Pricing model | Plan with included accounts, then per-account rates | Per linked account, tiered by volume |
| Free | $0, 5 email and calendar accounts, no credit card | 7-day trial, no credit card |
| Entry plan | $15/month (Essentials): 10 accounts, then $2.25 each | $55/month minimum for up to 10 accounts |
| Next tier | From $49/month (Pro): 25 accounts, then $2.00 each; $43 and $1.75 with annual billing | $5.50 per account (11–50), $5.00 (51–200) |
| Higher volume | Enterprise, volume band pricing | $4.50 per account (201–1,000), $4.00 (1,001–5,000), $3.50 (5,001+) |
| What counts as an account | One grant per connected email and calendar login | One linked identity; email and calendar on Gmail or Outlook count as one |
| Usage fees | Notetaker hours and Agent Account usage beyond plan | None per request, message or channel |
Unipile prices shown in US dollars; its page also lists euro prices. Both pricing pages checked October 13, 2026.
Worked example
A team connecting 50 accounts pays about $99 a month on Nylas Pro ($49 with 25 accounts included, plus 25 at $2.00), or about $87 with annual billing ($43 plus 25 at $1.75). The same 50 accounts cost $275 a month at Unipile (50 at $5.50). At 10 accounts, it’s $15 against $55.
At 100 accounts, Nylas Pro is about $199 a month and Unipile is about $500, based on Unipile’s own example of pricing every account at a single rate.
Providers and coverage
Both connect Gmail, Outlook and IMAP behind one auth flow. Unipile reaches further into messaging channels; Nylas reaches further into mail providers, calendar and contacts.

Frequently asked questions
Need more help?
Let’s talk!
Yes, if you need email, calendar, contacts, meeting recording or agent inboxes in one API. Unipile is the better fit if you need LinkedIn, WhatsApp, Instagram or Telegram messaging, which Nylas doesn’t offer. Some teams use both: Unipile for social channels and Nylas for email and calendar.
Nylas starts lower. Nylas Essentials is $15 a month for 10 connected accounts, then $2.25 per additional account. Unipile’s minimum is $55 a month for up to 10 accounts, then $5.50 per account from 11 to 50. At 50 accounts, Nylas Pro costs about $99 a month ($87 with annual billing) and Unipile costs $275. Unipile charges nothing per request or message.
Nylas connects Google, Microsoft 365, Yahoo (through OAuth), iCloud, IMAP and Exchange on-premises through one auth flow. Unipile’s FAQ lists Gmail, Outlook and IMAP; Yahoo and Apple accounts connect through IMAP with a password, and Exchange on-premises isn’t listed.
Not for email accounts. Unipile’s only contacts endpoint covers LinkedIn relations. Nylas has a Contacts API that reads and writes contact records across Google and Microsoft accounts, with webhooks when they change.
Yes, for email and calendar. Map Unipile accounts to Nylas grants, reconnect users through Nylas hosted auth or your own Google and Microsoft projects, and point your webhook handlers at Nylas triggers. OAuth tokens can’t transfer, so every user re-authorizes. Search calls need rewriting, and LinkedIn, WhatsApp, Instagram and Telegram flows stay on Unipile.
Both hold SOC 2 Type II reports. Nylas also holds ISO 27001 and ISO 27701 certifications and offers a pre-signed HIPAA BAA on all paid plans, on request, and an uptime SLA on Enterprise. Unipile hosts only in France, on Scaleway and OVHcloud. Nylas lets you choose the US (Iowa) or Europe (London) per application, so pick Unipile if your contract requires EU-only hosting, since London is outside the EU.
When your product reaches people on LinkedIn, WhatsApp, Instagram or Telegram as well as email, or when your data must stay inside the EU. Unipile also charges nothing per request or message, and retries webhooks five times against three delivery attempts at Nylas.
Compare five things: the providers and channels you need, how the API signals changes, how search works, how pricing scales per account, and which compliance reports you can obtain.
Conclusion
Both platforms unify email and calendar across providers behind one API. Unipile adds social and messaging channels and France-only hosting. Nylas adds contacts, Notetaker, Agent Accounts, more mail providers and lower published per-account prices.
Choose Nylas if your product centers on email, calendar, contacts or meeting data, you’re building agents that need their own inbox, or you want to start with fewer than 10 accounts without a $55 minimum.
Choose Unipile if you need LinkedIn, WhatsApp, Instagram or Telegram alongside email, or your contract requires all data to stay inside the EU.
