Hi I m using sendgrid to send mails with OTP and magic link

Question

Hi I m using sendgrid to send mails with OTP and magic link So sometimes user don t receive mails So in that case I want to use default supertokens mailing system as a callback to this issue Is that possible

rp · Answer

hey < Alen> how do you know if a user has not received the email Do you assume thats the case if they click on the resend button

Alen · Answer

no we get a response code with 400 or 500 error So based on that we want a fallback aproach

rp · Answer

right So in that case you can just call the original implementation of sendEmail and that should fallback on the default method

rp · Answer

this is assuming that the call to sendgrid and it returning the status is synchronous

Alen · Answer

yeah its synchronous So I have a custom body to be send how can override that

rp · Answer

So for that you need to use the smtp service we have and configure your smtp settings + define your custom body in there Then calling the original implementation will use the smtp service if you want to fallback on us sending the email then you can t customise the template

This is how I m sending the mail currently

Alen · Answer

If you see `sgMail send msg then response body => console log Email sent successfully console log response statusCode catch error => console error error ` If the `response statusCode` is 400 or 500 related then I want the mail to be send from supertokens

rp · Answer

Then do `originalImplementation sendEmail input `

Alen · Answer

Ok but you are saying we cant provide custome body then

rp · Answer

yea If you want us to send the email no custom body

rp · Answer

if you use the smtp service see docs then you can
