Will e-mails be delivered?

[mikaelsvensson]

Gmail has a number of limitations on how many e-mails can be sent during a certain time span. Will this be a problem if we want to send up to 100 mails at the same time?

Yes, it will be a problem if we use Gmail's SMTP service since we might not get notified (by Gmail) if mails are rejected/delayed/dropped. Look into using Mailgun instead (which doesn't have a daily send limit or their free plan, only a monthly limit).

Eftersom vi redan använder wp-mail-smtp så kan vi enkelt byta till, exempelvis, Mailgun för att skicka mejl. För att spara skickade mejl eller se "leveransinfo" så måste man köpa pro-versionen av wp-mail-smtp.
