Usage

Basic

EmailValidation() initialized with default thresholds.

use SendGridValidation\EmailValidation;
use SendGridValidation\Repository\SendGridApiRepository;

$validation = new EmailValidation(new SendGridApiRepository('api-key'));

$emailValid = $validation->validate('email@example.com'));

echo $emailValid->isValid; // true
echo $emailValid->isValidRisk; // true
echo $emailValid->isValidScore; // true
echo $emailValid->isDisposable; // false
echo $emailValid->hasSuggestion; //false
echo $emailValid->suggestion; // null

EmailValidation()->validate() returns an instance of EmailValidationDto()

EmailValidationDto()

• $isValid - Calculated true if validation result meets specified thresholds.
• $isValidRisk - Calculated true specified risk criteria
• $isValidScore - Calculated true if within minimum score threshold.
• $isDisposable - Calculated true if an email is considered to be disposable.
• $hasSuggestion - Calculated true if a suggestion is available.
• $suggestion - Calculated email suggestion if available.

class EmailValidationDto
{
    public bool $isValid = false;

    public bool $isValidRisk = false;

    public bool $isValidScore = false;

    public bool $isDisposable = false;

    public bool $hasSuggestion = false;

    public ?string $suggestion = null;
}

Advanced

EmailValidation() can be initialized with optional parameters to validate against developer specified thresholds.

• $allowRisky - When true, considers risky emails valid if other conditions are met.
• $allowDisposable- When true, considers disposable emails valid if other conditions are met.
• $checkValidScore - When true, checks SendGrid valid emails against the minimum score threshold.
• $minSCore - Default 0.30. considers emails invalid if the minimum score threshold is not met.

use SendGridValidation\EmailValidation;
use SendGridValidation\Repository\SendGridApiRepository;

$validation = new EmailValidation(
    new SendGridApiRepository($apiKey),
    true, // bool $allowRisky = true,
    true, // bool $allowDisposable = true,
    true, // bool $checkValidScore = false,
    EmailValidation::MIN_SCORE // float $minScore = self::MIN_SCORE (0.30)
);

$emailValid = $validation->validate($email);
