Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

46elks

  • It is a small company, so global route depth, redundancy and round-the-clock support do not match the large aggregators.
  • Its advantages are Nordic and regulatory, so an organisation sending mainly to other regions gains nothing and pays more per message than it would at scale elsewhere.
  • The feature set covers SMS, voice and numbers only, with no WhatsApp, RCS, email or fraud products, so multi-channel needs a second vendor.
  • Sending to the United States requires purchasing a number first, and US inbound messaging and mobile numbers are not available self-serve at all.
  • US A2P traffic also requires 10DLC registration with its own fees and carrier surcharges, making a small European vendor a poor fit for a US-focused business.

Auth0

  • Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
  • Advanced features like MFA and RBAC only available on paid Essentials tier and above
  • Ownership by Okta introduces risk that independent product roadmap may change

Answered from the vendors’ own pages

46elks: Why choose 46elks over Twilio?

Only for Nordic and regulatory reasons: local numbers, sender identity handling, a supplier regulated under Swedish electronic communications law, EU contracting, and support in your own time zone. On global reach and price at volume the large vendors win.

Auth0: How much does Auth0 cost?

Auth0 has a Free tier for up to 25,000 monthly active users (MAUs). Paid plans start at $35/month (Essentials B2C) and scale to $240/month (Professional B2C) and higher for Enterprise. Pricing scales with MAU usage.

46elks: Does 46elks publish its prices?

Yes, all of them, without a login, in Swedish kronor and euros. Swedish messages run about 0.047 euros per part and Swedish landline calls about 0.013 euros a minute.

Auth0: Does Auth0 include Multi-Factor Authentication?

No. MFA, RBAC (Role-Based Access Control), and premium support are not included in the free tier and require upgrading to paid Essentials plans or higher.

Source
46elks: Is it suitable for sending to the United States?

Poorly. You must buy a number before you can send there, US inbound messaging and mobile numbers are not self-serve, and US A2P traffic requires 10DLC registration with its own fees and carrier surcharges.

Auth0: Is Auth0 independent or part of a larger company?

Auth0 was acquired by Okta in May 2021 for $6.5 billion. It now operates as a subsidiary business unit within Okta, but maintains its own brand and operations.

Source
Auth0: Who should use Auth0 vs Okta?

Auth0 is developer-focused and serves customer identity use cases (B2C). Okta serves workforce identity (B2B) and has broader enterprise features. Auth0 now serves both markets post-acquisition but maintains its developer-friendly positioning.
