1) Incorrect Email Format or Typo
Paradoxically, this is the most common cause. Please double-check your email address carefully when entering it.
Common mistakes include:
gmail.con or gnail.com (typing "N" instead of "M")
gmail.cz or outlook.de (wrong domain suffix like cz/de instead of com)
[email protected] (missing letter in the name)
[email protected] (missing letter in the domain)
[email protected] (typo in the name)
2) Email Went to Spam
Check your spam or junk folder in your email client.
3) Email Provider Restrictions
This is typical for corporate domains (e.g., [email protected]), where you may have various email server providers.
These restrictions may be set by whoever built your website or by your IT department -- there could be specific rules, special settings, or even configuration errors.
The most common providers like gmail.com and outlook.com are generally reliable and shouldn't cause such issues.
